Résumé

By consulting the ancient and modern literature, the textual research of Pharbitidis Semen has been conducted to clarify the name, origin, distribution of production areas, quality specification, harvesting, processing and so on, so as to provide reference for the development and utilization of the relevant famous classical formulas. Through textual research, it can be seen that Pharbitidis Semen was first published in Mingyi Bielu(《名医别录》), and all dynasties have taken Qianniuzi as the correct name. Based on the original research, the main source of Pharbitidis Semen used in previous dynasties is the dried mature seeds of Pharbitis nil, which is consistent in ancient and modern times. The white Pharbitidis Semen appearing in Compendium of Materia Medica(《本草纲目》) from Ming dynasty is similar to the present P. purpurea. It is produced all over the country, and the quality is better if the particles are full and free of impurities. In ancient times, the harvesting time was mostly in the September. Now it is autumn. The fruits are ripe and harvested, dried to remove impurities for standby. In ancient times, the processing methods of Pharbitidis Semen were mainly wine steaming, steaming and frying until half cooked and grinding the head and end. In modern times, they have been simplified to stir-frying method. The nature, taste, meridian tropism and their effects also change supplements with the deepening of practice. Before the Ming dynasty, they were all bitter, cold and toxic. In the Ming dynasty, there appeared the characteristics of pungent, hot and small poisonous. The efficacy has evolved from controlling low Qi, curing foot edema, removing wind toxin, and facilitating urination to facilitating water and defecation, eliminating phlegm and drinking, and eliminating accumulated insects. The main clinical contraindications are those with weak spleen and kidney, those with weak spleen and stomach, pregnant women, and should not be used with croton and croton cream. Based on the textual research, it is suggested that when developing the classic famous formula with Pharbitidis Semen as the main raw material in the future, it is clear that the source should be the dried mature seeds of Pharbitis nil(black product is its black-brown seeds, white product is its beige seeds). The processing requirements indicated in the original formula are all processed according to the requirements, and the raw product is recommended to be used as medicine if not specified.

Résumé

ObjectiveTaking Achyranthis Bidentatae Radix(ABR) from different origins as samples, to quantitatively analyze the chemical composition and chromaticity of ABR with different processing degrees, and clarify the correlation and change law between color and composition in the processing process of ABR, so as to provide reference for the quality evaluation of processed products of ABR. MethodThe colorimeter is used to measure the chromaticity values of three kinds of processing degrees of ABR in different origins to show the color value change trend during the processing process, and the color parameters of wine-processed and salt-processed products of ABR with different processing degrees were analyzed by principal component analysis(PCA), orthogonal partial least squares-discriminant analysis(OPLS-DA) and other analysis methods. The contents of eight representative components of ABR were measured by high performance liquid chromatography(HPLC), the correlation between chromaticity and each representative component was analyzed by Pearson correlation analysis, and the applicability of the selected eight representative components was further verified by Fisher linear discriminant analysis, and the wine-processed and salt-processed products of ABR with different processing degrees were grouped according to the degree of processing, and 48 samples of wine-processed and salt-processed products with different processing degrees were used as training samples. Taking the contents of 5-hydroxymethylfurfural, polypodine B, β-ecdysterone, 25R-inokosterone, 25S-inokosterone, ginsenoside Ro, chikusetsusaponin Ⅳa and polysaccharides as variables, the discriminant function was established respectively, and 12 samples of wine-processed and salt-processed products of ABR with different processing degrees were back-tested to verify the discriminant function and test the reliability of the function. ResultPCA and OPLS-DA results showed that ABR samples with different processing degrees were classified into clusters, and the results could significantly distinguish different processed products. During the process of wine and salt processing, the contents of 5-hydroxymethylfurfural, ginsenoside Ro, and chikusetsusaponin Ⅳa gradually increased with the deepening of the processing degree, while the contents of polypodine B, β-ecdysterone, 25R-inokosterone, 25S-inokosterone and polysaccharides showed a gradual decreasing trend, indicating these 8 components increased and decreased to different degrees in the process of wine and salt processing. The results of Pearson correlation analysis showed that the 5-hydroxymethylfurfural content of the samples with different processing degrees of wine-processed and salt-processed products were negatively correlated with the brightness value(L*) and the total color difference value(E*ab)(P<0.01), and positively correlated with the red-green value(a*) and the yellow-blue value(b*)(P<0.01), and that the content of polypodine B and polysaccharides were positively correlated with L* and E*ab(P<0.01). The discriminant functions of wine-processed and salt-processed products of ABR were established by Fisher linear discriminant analysis, and their accuracy rates in the training samples were 93.75% and 95.83%, respectively. Twelve test samples of wine-processed and salt-processed products with different processing degree were back substitution, and the correct rate was 100%. ConclusionThe trend of composition and color changes of ABR with different processing degrees in different production areas is relatively consistent, and the color value can better distinguish ABR with different processing degrees, and the color of ABR is related to some representative components in the processing process, indicating that the color can provide reference for the identification of the processing degree of ABR and the prediction of component content.

Résumé

This article systematically analyzes the historical evolution of the origin, scientific name, medicinal parts, quality evaluation, harvesting and processing and other aspects of Tsaoko Fructus by consulting ancient materia medica, medical books, prescription books in the past dynasties and combining with the modern literature, so as to provide a basis for the development and utilization of famous classical formulas containing Tsaoko Fructus. According to the research, the name of Caoguo(草果) was first used in the Taiping Huimin Heji Jufang(《太平惠民和剂局方》) in the Northern Song dynasty, Tsaoko Fructus is the correct name of the herbal medicine in all dynasties, and there are also aliases such as Caokou, Doukou, Loukou, Laokou and Caodoukou. The mainstream source of Tsaoko Fructus used in the past dynasties is the dried mature fruit of Amomum tsaoko of Zingiberaceae, but Tsaoko Fructus was often used as a nickname for Amomi Fructus Rotundus or Alpiniae Katsumadai Semen during the Song dynasty. Bencao Pinhui Jingyao(《本草品汇精要》) in the Ming dynasty was the earliest materia medica that recorded Tsaoko Fructus as a separate medicinal herb in sections. Under the influence of early ancient books, there were some books that confused Tsaoko Fructus with other Zingiberaceae plants during the Qing dynasty, it was not until modern times that Tsaoko Fructus was distinguished from other plants. The origin of Tsaoko Fructus is Yunnan and Guangxi, and then gradually expanded to Guizhou and other places. Now Yunnan is the province with the largest planting area of Tsaoko Fructus, and has become the main producing area. Since modern times, it has been recorded in the literature that the quality of Tsaoko Fructus is mainly characterized by large, full, red-brown and strong in smell. According to ancient records, the harvest time of Tsaoko Fructus was in the eighth month of the lunar calendar, and they were mostly used for peeling or simmering. Currently, the harvest period of Tsaoko Fructus is October to November, and then sun-dried or dried after harvesting. The records of the properties and functional indications of Tsaoko Fructus are basically consistent with the ancient and modern documents, which is warm in nature, pungent in flavor, belonging to the spleen and stomach meridians, moderate in dryness and dampness, intercepting malaria and eliminating phlegm, used for internal resistance of cold and dampness, abdominal distension and pain, fullness and vomiting, malaria cold and fever, and plague fever. Based on the research results, it is suggested that A. tsaoko should be used as the medicinal base for the development of famous classical formulas containing Tsaoko Fructus, processing method can be according to the requirements of the prescription, and if the requirements of concoction are not indicated, it can be used in the form of raw products.

Résumé

In order to provide basic information for the utilization and development of famous classical formulas containing Bletillae Rhizoma, this article systematically analyzes the historical evolution of the name, origin, harvesting and processing of Bletillae Rhizoma by reviewing the ancient materia medica, prescription books, medical books and modern literature. The research results showed that Baiji(白及) was the main name, some scholars took Baiji(白芨) as its main name, and there were many other names such as Baiji(白给), Baigen(白根), Baiji(白苙). The mainstream source of Bletillae Rhizoma was the tubers of Bletilla striata, and drying, large, white, solid, root-free and skin removed completely were the good quality standards. With the promotion of wild to cultivated medicinal materials, there were certain differences between their traits, and the quality evaluation indexes should be adjusted accordingly. The origin of records in the past dynasties was widely distributed, with Guizhou and Sichuan having high production and good quality in modern times. The harvesting period is mostly in spring and autumn, and harvested in autumn was better. The processing and processing technology is relatively simple, and it was used fresh or powdered in past dynasties, while it is mainly sliced for raw use in modern times. Based on the results, it is suggested that the tubers of Bletilla striata of Orchidaceae should be used in the famous classical formulas, and it should be uniformly written as Baiji(白及). And if the original formula indicates the requirement of processing, it should be operated according to the requirement, if the requirement of processing is not indicated, it can be used in raw form as medicine.

Résumé

The quality evaluation of the blind method is to evaluate the clinical blind data obtained from clinical trials adopting the blind method and judge the effectiveness of the blind method by investigating the blind effect of different blind objects. A successful blind method can avoid the influence of subjective factors on the test results of subjects and researchers to a certain extent. The quality evaluation of the blind method can reflect not only the effectiveness of the blind method but also the accuracy and credibility of clinical trial results. In recent years, randomized controlled trials have been widely used in the evaluation of the clinical efficacy of traditional Chinese medicine (TCM), but the quality of the implementation of blind methods is uneven, and the evaluation criteria have not yet been formed. In this paper, the data collection methods, calculation principles, advantages, and disadvantages of two quantitative quality evaluation methods of blind methods, namely James Blinding Index (JBI) and Bang Blinding Index (BBI), were introduced. The two indexes were analyzed in a randomized controlled trial of acupuncture and moxibustion to relieve postoperative oral pain. The calculation process of the results was demonstrated by R software and visualized by forest map. At the same time, a tool table was designed to facilitate the collection of evaluation data of blind methods in TCM clinical trials at different stages. Finally, the necessity and feasibility of quality evaluation of blind method in TCM research were discussed to provide a basis for evaluating and improving the quality of blind method implementation in TCM clinical trials.

Résumé

By consulting the ancient Chinese herbal books, medical books and formularies of the past dynasties, and combining with modern research data, this paper makes a systematic textual research on the name, origin, place of origin, traditional quality evaluation, harvesting and processing of Selaginellae Herba, so as to provide a basis for the development and utilization of the relevant famous classical formulas. According to the textual research, Juanbai is the correct name of the herbal medicine in all dynasties, and there are also aliases such as Baozu, Qiugu, Jiaoshi and Jiusi Huanhuncao. The origin of Selaginellae Herba in the ancient herbal books was Selaginella tamariscina in all dynasties. Since the Republic of China, S. pulvinata has been gradually used as another origin of Selaginellae Herba. In ancient times, the producing area of S. tamariscina was mainly in Shandong, Hebei, Henan, Shaanxi, Jiangsu and Sichuan, etc. Nowadays, it is produced all over the country. S. pulvinata is mainly produced in Guangxi, Fujian, Sichuan, Guizhou, Yunnan, Hebei and so on. Since the recent times, it is concluded that the quality of the green color, complete and unbroken is good. Before the Qing dynasty, it was recorded that the harvesting time of Selaginellae Herba was generally from April to July, and it was expanded to all year round since the Qing dynasty. After harvesting, remove the sediment(sand and mud), cut off the fibrous roots and dry in the shade or in the sun. The processing methods in all dynasties were mainly carbonizing by stir-frying and stir-bake to brown, and some ancient books contained the processing method of brine boiling, which was rarely used in modern times. Based on the results, it is recommended that S. tamariscina should be used as the base material of Selaginellae Herba. Because of more impurities, it should be fully purified to ensure the cleanliness of the herb, and the processing method can be based on the prescription requirements, if the processing requirements are not specified, the raw products can be used, charcoal products is recommended for use as an hemostatic.

Résumé

ObjectiveBased on the experience of traditional quality evaluation, the quality of Atractylodis Macrocephalae Rhizoma(AMR) with different production methods such as direct seeding, transplanting after seedling raising, topping and non-topping, and difference in growth years was compared. MethodVernier caliper was used to measure the trait data of AMR in different production methods. Paraffin sections of AMR with different production methods were made by saffron solid green staining, and the microstructure was observed. The contents of water-soluble and alcohol-soluble extracts in AMR with different production methods were determined according to the 2020 edition of Chinese Pharmacopoeia. The content of water-soluble total polysaccharides in AMR with different production methods was detected by sulfuric acid-anthrone method. Fiber analyzer was used to detect the content of fiber components in AMR with different production methods. The contents of monosaccharides, oligosaccharides and some secondary metabolites in AMR with different production methods were detected by ultra performance liquid chromatography(UPLC), and the differences of chemical components were compared by multivariate statistical analysis methods such as principal component analysis(PCA) and partial least squares-discriminant analysis(PLS-DA). ResultIn terms of traits, the 3-year-old AMR with direct seeding and without topping was close to the high-quality AMR with "phoenix-head and crane-neck, strong sweetness and clear aroma" recorded in ancient materia medica, followed by the 3-year-old AMR with topping after transplanting, while the 2-year-old AMR with topping after transplanting with high market circulation rate was generally fat and strong with mild odor. In the microscopic aspect, the arrangement of xylem vessels and fiber bundles in the 3-year-old samples formed two obvious rings. Compared with the 2-year-old samples cultivated in Bozhou and Zhejiang, the 3-year-old samples without topping after transplanting had more wood fibers. In terms of chemical composition, the contents of 70% ethanol extract, fructose, glucose, sucrose, 1-kestose, atractylenolide Ⅰ, chlorogenic acid, neochlorogenic acid, cryptochlorogenic acid and other components in 3-year-old AMR with direct seeding and without topping were significantly higher than those in the other three samples(P<0.05). The contents of cellulose, 70% ethanol extract, sucrose, atractylenolide Ⅰ, atractylone and other components in 3-year-old AMR with topping after transplanting were significantly higher than those in the 2-year-old AMR with high market circulation rate(P<0.05), while the contents of water-soluble extract and water-soluble total polysaccharides in 2-year-old samples with topping after transplanting were significantly higher than those in the 3-year-old AMR with topping after transplanting, direct seeding and without topping(P<0.05). ConclusionUnder the current mainstream production mode, too much manual intervention makes AMR heavily enriched in polysaccharides and increased the yield, but the accumulation of sweet substances, fragrant substances and fiber substances is insufficient, which affects its quality. The current quality standard of AMR has some shortcomings in guiding the high quality production of it, it is suggested to revise the quality standard of AMR, supplement the quantitative analysis of secondary metabolites, and strengthen the production of imitation wild AMR.

Résumé

ObjectiveBased on the quality evaluation experience of "it is better to have a fragrant and strong aroma" summarized by materia medica of past dynasties, the chemical components of Sojae Semen Nigrum(SSN) and Sojae Semen Praeparatum(SSP) were systematically compared and analyzed, and the main fermentation products in different fermentation time were quantitatively analyzed, so as to clarify the transformation law of internal components in the processing process and provide scientific basis for the modern quality control of SSP. MethodUltra performance liquid chromatography-quadrupole tandem time-of-flight mass spectrometry(UPLC-Q-TOF-MS) was used for the structural identification of the chemical constituents of SSN and SSP, and with the aid of Progenesis QI v2.3 software, the negative ion mode was employed for principal component analysis(PCA) pattern recognition, and the data were analyzed with the aid of orthogonal partial least squares-discriminant analysis(OPLS-DA) for two-dimensional data to obtain S-plot, and components with |P|>0.1 were selected as the differential constituents. The contents of isoflavonoids in SSP during fermentation was determined by UPLC, and the samples were taken every 8 h in the pre-fermentation period and every 2 d in the post-fermentation period, and the dynamic changes of isoflavonoid contents in different fermentation stages were analyzed. The contents of amino acids and nucleosides in SSP and SSN from different fermentation stages were quantitatively analyzed by phenyl isothiocyanate(PITC) pre-column derivatization and high performance liquid chromatography(HPLC) gradient elution, and the contribution of flavor substances to the "delicious" taste of SSP was discussed by taste intensity value(TAV). ResultA total of 19 kinds of differential components were screened out, mainly soybean saponins and isoflavones, and their contents decreased significantly or even disappeared after fermentation. In the pre-fermentation process of SSP, glycoside bond hydrolysis mainly occurred, and isoflavone glycosides in SSN were degraded and converted into the corresponding aglycones, the content of flavor substances such as amino acids increased gradually. In the post-fermentation process, protein degradation mainly occurred, after 8 d of post-fermentation, the content of isoflavones was basically stable, while the total content of amino acids increased by 8-40 times on average. Different amino acids form the special flavor of SSP, such as the TAV of glutamate is always ahead of other flavor substances, and sweet substances such as alanine and valine have made relatively great contributions to SSP. ConclusionBased on the law of constituent transformation, combined with the traditional evaluation index of "fragrant and strong", it is difficult to control the fermentation degree of SSP by the existing standards in the 2020 edition of Chinese Pharmacopoeia. It is suggested that description of the characteristics of SSP be refined and changed to "fragrant, delicious and slightly sweet", and at the same time, the post-fermentation index compounds such as glutamic acid, alanine and valine should be added as the quality control indicators of SSP, so as to standardize the production process and improve the quality of SSP.

Résumé

ObjectiveBased on the traditional quality evaluation methods summarized in previous dynasties, this paper systematically contrasted cultivated Astragali Radix(CA) and wild-simulated Astragali Radix(WA) from the aspects of character, microstructure and chemical composition by modern technological means. MethodThe collected CA and WA were compared in characters and microscopic characteristics in cross section, and comparative analysis were performed on the contents of cellulose, extracts, carbohydrate, total flavonoids, total saponins, etc. Then ultra-high performance liquid chromatography-quadrupole-time-of-flight mass spectrometer(UPLC-Q-TOF-MS) and desorption electrospray ionization mass spectrometry imaging(DESI-MSI) were used to comparatively analyze the secondary metabolites and their spatial distributions in the xylem and phloem of CA and WA. ResultIn terms of characters, the characters and sectional features of WA was consistent with the characteristics of high-quality Astragali Radix, while the CA was quite different from the traditional high-quality Astragali Radix. In terms of microscopy, the phellem layer of CA was thin, and the section fissures were mostly distributed through the cambium in a long strip shape without obvious growth ring characteristics. The cork layer of WA was thick, and the cracks in the section were distributed in the center of the xylem and the outer edge of the phloem in an irregular cavity shape. The cambium was tight without cracks, and had obvious characteristics of a growth ring. In terms of chemical composition, the contents of water-soluble extract, 80% ethanol extract and sucrose of CA was significantly higher than those of WA, while the contents of total saponins, lignin and hemicellulose were significantly lower than those of WA. And the contents of 100% ethanol extract, total polysaccharides and total flavonoids in both of them were generally similar, but slightly higher in WA. The contents of 2 kinds of monoacyl-substituted flavonoid glycosides in the xylem of WA was significantly higher than those of CA, while the contents of 2 kinds of flavonoid aglycones and one flavonoid glycoside were on the contrary. The contents of 7 saponins in phloem of WA were significantly higher than those of CA. ConclusionThere are significant differences between CA and WA in characters, microstructure and chemical components, in which CA has a fast growth rate and a short planting period, and the primary metabolites such as water-soluble extracts and sucrose are more enriched, which is the reason for its firm texture and sweetness being significantly higher than those of WA. However, the contents of lignin, hemicellulose and some secondary metabolites in WA are significantly higher than those in the CA, which are close to the traditional description of characters and quality. Based on the results of this study, it is suggested to strengthen the production of WA, improve the supply capacity of WA, and gradually upgrade the current standard. It is recommended to increase the contents of monoacyl-substituted flavonoid glycosides, total saponins and other indicators that can characterize different production methods, so as to guide the high-quality production of Astragali Radix.

Résumé

Traditional Chinese medicine dispensing granules(TCMDGs)is the new type of decoction pieces with the development of modernization of TCM, which has received mixed opinions since its practical application. In 2021, the national departments issued Announcement on Ending the Pilot Work of TCMDGs, marking the end of the 28-year pilot work of TCMDGs, and eligible TCM enterprises can produce TCMDGs after filing. However, this does not mean that the preparation process, quality standard and efficacy research of TCMDGs have been developed and matured, on the contrary, there are still some problems that need to be solved and gradually improved. For example, in the production process, there are problems such as unclear, unified and non-standardized preparation parameters. In terms of quality control, there are some problems such as lack of producing area regulation, variety selection and processing specification. In terms of consistency evaluation with traditional decoction, there are problems such as unclear relationship between the chemical constituents and pharmacological effects of the two. Therefore, in view of some prominent problems of TCMDGs at present, this paper takes the published literature as the main data source and combines the specific requirements of the code or technical standards such as the 2020 edition of Chinese Pharmacopoeia, Publicity of the Unified Standard on the Varieties of TCMDGs, Quality Control and Standard Formulation Technical Requirements of TCMDGs. The production process of TCMDGs, the origin and variety of raw materials, the processing of decoction pieces, the quality control standard and the consistency evaluation of formula granules and traditional decoction were sorted out and visualized by literature mining, data analysis and list comparison. Based on the analysis results, the following suggestions were made. In terms of preparation process, the completeness and standardization of process parameters should be strengthened. In terms of quality evaluation, attention should be paid to the relationship between the authenticity, variety, processing and quality of medicinal materials. In the consistency evaluation of formula granules and traditional decoction, the deep difference and mechanism between TCMDGs and traditional decoction were discussed by combining structural Chinese medicine, quality marker(Q-Marker) theory and physicochemical characterization, so as to provide reference for the application and development of TCMDGs.

Résumé

In this paper, the name, origin, quality evaluation, producing area and processing methods of Lablab Semen Album in the famous classical formulas were researched by reviewing the ancient materia medica, medical books, prescription books and modern literature. The results showed that the name of Lablab Semen Album in the past dynasties was mostly derived from its shape and color, called Biandou and Baibiandou. The mainstream origin used in the past dynasties was Lablab purpureus, the medicinal parts were mainly white mature seeds, with the addition of the leaves in the Song dynasty and the flowers in the Ming dynasty. Since modern times, the authentic producing areas of Lablab Semen Album are Suzhou, Zhejiang and other places, and now mainly produced in Chuxiong and Xinping, Yunnan and Panzhihua, Sichuan. The traditional quality evaluation of Lablab Semen Album is evaluated as large, solid, full and white. The harvesting time of this herb is recorded from the eighth to the ninth lunar month in related literature, the pods are picked when the seeds are ripe, and the seeds are dried in the sun. In ancient times, the processing of Lablab Semen Album mainly consisted of frying the seeds with skin and then pulverizing for use, or soaking and peeling seeds for raw use. Based on the conclusion of the textual research, it is recommended that the seeds or flowers of the white flowering plants of L. purpureus, a member of the leguminosae, should be used in the famous classical formulas, and the dried seeds or dried flowers of Lablab Semen Album can be used as medicine if the formula did not clearly indicate processing requirements.

Résumé

By reviewing ancient materia medica, medical and prescription books, combined with modern literature, the textual research of Stephaniae Tetrandrae Radix has been conducted to verify the name, origin, producing area, harvesting and processing methods. Through textual research, the results show that the mainstream name of this herb recorded in the past dynasties is Fangji, which is also called Hanzhong Fangji because it is produced in Hanzhong city, and after the Tang dynasty, it was gradually divided into Hanfangji and Mufangji, and there is the saying that Han Zhushuiqi, Mu Zhufengqi. The names of Fenfangji and Guangfangji were first seen in the republic of China. In addition, Fenfangji was once distributed in Hankou, so it was also known as "Hanfangji", which is easily confused with the traditional Hanzhong Fangji for short. Based on the original research, it is concluded that Aristolochia heterophylla(Hanzhong Fangji)is the mainstream of Stephaniae Tetrandrae Radix used in the Qing dynasty and before, and the application history of Cocculus orbiculatus can be traced back to before the Tang dynasty. After the Ming dynasty, Stephania tetrandra gradually became another main origin, and in the Republic of China, A. fangchi was used as a medicine for Stephaniae Tetrandrae Radix, but in modern times it was banned because it contained aristolochic acid as a toxic ingredient, and S. tetrandra has become the mainstream legal origin. The traditional production area of Hanzhong Fangji is Hanzhong, Shaanxi province, while today the mainstream of S. tetrandra is manly produced in Jiangxi and other places. Based on the quality evaluation research, the quality of Hanzhong Fangji is better with the radial texture of section used as radial solution, yellow solid and fragrant. Fenfangji with solid quality, white inside, powdered enough, less fiber and radiating texture is better. From the harvesting and processing research, the root of Fangji is mostly harvested in spring and autumn, and the outer bark should be removed in some literature. Before the Ming dynasty, this herb was dried in the shade, and after the Ming dynasty, it was dried in the sun. The modern production processing of Fangji is to harvest it in autumn, wash it, remove the rough bark, dry it to half dry, cut it into sections, and then cut it longitudinally if it is large, and dry it. Based on the results, combined with current studies on the toxicity of aristolochic acid and influencing factors such as commercial circulation, it is suggested that S. tetrandra should be used as the origin of Fangji, the processed products are selected according to the prescription requirements, and those without specified requirements can be processed by referring to the raw products in the 2020 edition of Chinese Pharmacopoeia.

Résumé

By reviewing ancient materia medica and combining with modern literature, the textual research of Magnoliae Flos has been conducted to verify the name, origin, producing area, harvesting and processing methods, in order to provide basis for the selection and use of this herb in the development of famous classical formulas. After the textual research, it could be seen that the correct name of Magnoliae Flos was Xinyi in the past dynasties, meaning spicy flower buds. The main original plants used in past dynasties are Magnolia denudata and M. biondii. The history of the research on its scientific name in recent times is complicated, many foreign scholars have given several different scientific names, but most of them are inconsistent with the actual situation of Magnoliae Flos used in ancient China, because foreign scholars failed to collect the original plants of Magnoliae Flos for accurate identification. Before the Ming dynasty, Magnoliae Flos was mainly produced in Shaanxi, and then the recorded production areas gradually increased. After the founding of the People's Republic of China, the products produced in Henan named M. biondii were highly respected, and Henan was regarded as authentic producing area, and because of the collection and distribution through Yuzhou, it was customarily called Huichunhua. In ancient times, the harvesting period of Magnoliae Flos mostly concentrated in the first and second months of the lunar calendar, and the flower buds of M. biondii were also recommended to be used as medicine, but nowadays the flower buds are mostly collected in winter and spring, and those with dry buds, large size, yellow-green color, tight inner petals, fragrant smell, and no impurities are preferred. In the past dynasties, raw products were the mainstream, and there were also frying, soaking and so on. Based on the results, it is suggested that the flower buds of M. biondii should be used in the development of famous classical formulas. If the original formula does not specify the processing requirements, the raw products can be used as medicine.

Résumé

By reviewing ancient materia medica, medical books and modern literature, this paper conducted a systematic research on name, origin, scientific name evolution, producing area, quality, harvesting and processing methods of Alpiniae Officinarum Rhizoma. The results showed that Alpiniae Officinarum Rhizoma was first published in Mingyi Bielu, and its correct name was Gaoliangjiang. The mainstream origin of Alpiniae Officinarum Rhizoma used in the past dynasties is Alpinia officinarum, which is used to this day, while it used to be mixed with A. galanga because of the similar name and morphology. Alpiniae Officinarum Rhizoma produced in Danzhou and Leizhou was considered to be better in ancient times, and now it mainly produced in Guangdong, Guangxi and Hainan provinces. In addition, it has been concluded that Alpiniae Officinarum Rhizoma with reddish brown, sturdy and firm character, wrinkled skin, convex flesh, aromatic and spicy taste, and few branches is the best. In ancient times, Alpiniae Officinarum Rhizoma was commonly harvested in February and March, whereas it generally harvested in late summer or early autumn at present, and wild products are usually harvested before the rainy season in May. The main processing methods of Alpiniae Officinarum Rhizoma are cleansing and cutting, and some other methods are stir-frying or mixing with auxiliary materials. Based on the research results, it is suggested that the raw products of A. officinarum rhizomes or its processed products according to prescription requirements should be used in the development of famous classical formulas containing Alpiniae Officinarum Rhizoma.

Résumé

By reviewing ancient materia medica, medical books, prescription books and modern literature, the herbal textual research of Sanguisorbae Radix has been conducted to verify the name, origin, evolution of scientific name, producing area, harvesting time, quality evaluation and processing methods. Through herbal textual research, the name of Diyu was first published in the Shennong Bencaojing, and has been used as the proper name of this herb for generations since then. The origin of the mainstream Diyu of previous generations was the roots of Sanguisorba officinalis or its variant S. officinalis var. longifolia. In ancient times, this herb was preferred to those with soft and fat roots, according to this characteristic, its origin should be S. officinalis var. longifolia. In modern literature, the root is preferred to those with thick, hard, pink or red sections, without rhizomes or fibrous roots, according to these characteristics, its origin should be S. officinalis. Most of the time, the past generation used Diyu directly. Occasionally, Sanguisorbae Radix was processed by frying with vinegar, baking or other methods. Since the Qing dynasty, the carbonized products has appeared and has continued to now. Based on research, it is recommended that the roots of S. officinalis var. longifolia should be used in the development of famous classical formulas, and the processing method should be selected according to the formula.

Résumé

In this study, ultra-performance liquid chromatography-quadrupole/time-of-flight mass spectrometry(UPLC-Q-TOF-MS) and gas chromatography-mass spectrometry(GC-MS) were combined with non-targeted metabonomic analysis based on multivariate statistics analysis, and the content of five indicative components in nardosinone was determined and compared by UPLC. The main chemical components of Nardostachyos Radix et Rhizoma with imitative wild cultivation and wild Nardostachyos Radix et Rhizoma were comprehensively analyzed. The results of multivariate statistical analysis based on liquid chromatography-mass spectrometry(LC-MS) and GC-MS were consistent. G1 and G2 of the imitative wild cultivation group and G8-G19 of the wild group were clustered into category 1, while G7 of the wild group and G3-G6 of the imitative wild cultivation group were clustered into category 2. After removing the outlier data of G1, G2, and G7, G3-G6 of the imitative wild cultivation group were clustered into one category, and G8-G19 of the wild group were clustered into the other category. Twenty-six chemical components were identified according to the positive and negative ion modes detected by LC-MS. The content of five indicative components(VIP>1.5) was determined using UPLC, revealing that chlorogenic acid, isochlorogenic acid A, isochlorogenic acid C, linarin, nardosinone, and total content in the imitative wild cultivation group were 1.85, 1.52, 1.26, 0.90, 2.93, and 2.56 times those in the wild group, respectively. OPLS-DA based on GC-MS obtained 10 diffe-rential peaks. Among them, the relative content of α-humulene and aristolene in the imitative wild cultivation group were extremely significantly(P<0.01) and significantly(P<0.05) higher than that in the wild group, while the relative content of 7 components such as 5,6-epoxy-3-hydroxy-7-megastigmen-9-one, γ-eudesmol, and juniper camphor and 12-isopropyl-1,5,9-trimethyl-4,8,13-cyclotetrade-catriene-1,3-diol was extremely significantly(P<0.01) and significantly(P<0.05) lower than that in the wild group, respectively. Therefore, the main chemical components of the imitative wild cultivation group and wild group were basically the same. However, the content of non-volatile components in the imitative wild cultivation group was higher than that in the wild group, and the content of some volatile components was opposite. This study provides scientific data for the comprehensive evaluation of the quality of Nardostachyos Radix et Rhizoma with imitative wild cultivation and wild Nardostachyos Radix et Rhizoma.

Résumé

From the perspective of market classification of Cnidii Fructus, this paper revealed the scientific connotation of evaluating the quality grade of Cnidii Fructus by its appearance traits. Thirty batches of Cnidii Fructus in different grades were selected as the research objects. The canonical correlation analysis and principal component analysis(PCA) were used to explore the measurement values of 15 appearance traits and intrinsic content indexes. The results of correlation analysis showed that except the aspect ratio, the 5 appearance trait indexes(length, width, 1 000-grain weight, broken grain weight proportion, and chroma) and 9 internal content indexes(the content of moisture, total ash, acid insoluble ash, osthole, imperatorin, 5-methoxy psoralen, isopimpinellin, xanthotoxin, and xanthotol) showed significant correlation to varying degrees. In addition, there was a significant positive correlation between the first typical variable U_1 composed of appearance traits and the first typical variable V_1 composed of internal content indexes(CR_1=0.963, P<0.01). The results of PCA showed that the classification results of appearance traits for 30 batches of Cnidii Fructus were consistent with the actual information of the samples. Under the same analysis conditions, 30 batches of Cnidii Fructus were reclassified by 9 groups of internal content indexes, and the analysis results were consistent. From the classification standard of the appearance traits of the system study, the statistical results of 6 appearance traits of Cnidii Fructus showed a correlation with grades. There was a good correlation between the appearance and the internal content of Cnidii Fructus, and the appearance quality effectively predicted the level of the internal content. There is a certain scientific basis for the quality classification of Cnidii Fructus by main appearance traits. Appearance classification can replace quality grading to realize the "quality evaluation through morphological identification" of Cnidii Fructus.
