ABSTRACT
Bungarus Parvus, a precious animal Chinese medicinal material used in clinical practice, is believed to be first recorded in Ying Pian Xin Can published in 1936. This study was carried out to analyze the names, geographical distribution, morphological characteristics, ecological habits, poisonousness, and medicinal parts by consulting ancient Chinese medical books and local chronicles, Chinese Pharmacopeia, different processing standards of trditional Chinese medicine(TCM) decoction pieces, and modern literatures. The results showed that the earliest medicinal record of Bungarus Parvus was traced to 1894. In 1930, this medicinal material was used in the formulation of Annao Pills. The original animal, Bungarus multicinctus, was recorded by the name of "Bojijia" in 1521. The morphological characteristics, ecological habits, and poisonousness of the original animal are the same in ancient and modern records. The geographical distribution is similar between the ancient records and modern documents such as China Medicinal Animal Fauna. The dried body of young B. multicinctus is used as Bungarus Parvus, which lack detailed references. As a matter of fact, it is still inconclusive whether there are differences between young snakes and adult snakes in terms of active ingredients, pharmacological effects, and clinical applications. This study clarified the medicinal history and present situation of Bungarus Parvus. On the basis of the results, it is suggested that systematic comparison on young and adult B. multicinctus should be carried out to provide references for revising the medicinal parts of B. multicinctus.

BACKGROUND: Osteoporosis (OP) is considered as one of the major comorbidities of rheumatoid arthritis (RA), and is responsible for fragility fracture. However, there is currently no effective treatment for RA complicated with OP. Tubson-2 decoction (TBD), a Mongolian medicine also known as Erwei Duzhong Decoction, has been shown to exert a preventive effect on post-menopausal osteoporosis (PMOP). The preventive effects of TBD on RA-induced OP, as well as the bioactive compound responsible and the underlying mechanisms, remain to be elucidated. OBJECTIVE: To explore the effects of TBD on RA-induced OP in vivo, and to elucidate the mechanism of isochlorogenic acid A (ICA), the effective component of TBD, in vitro. METHODS: To evaluate the anti-arthritic and anti-osteoporotic effects of TBD, we conducted H&E straining and safranine O/fast green, TEM, immunohistochemistry (IHC), bone histomorphometry, micro-CT imaging, and biomechanical testing in collagen induced arthritis (CIA) rats. The active ingredient in TBD was identified using network pharmacology and molecular docking. The identification was supported by in vivo IHC assay, and further confirmed using qRT-PCR, Western blot, and SEM analysis in TNF-α-treated MH7A cells and/or in LPS-exposed RAW264.7 cells. RESULTS: Oral administration of TBD attenuated the severity of arthritis and osteopenia as well as poor bone quality, in CIA rats. Additionally, TBD and the positive control, tripterygium glycosides (TG), exhibited similar effects in reducing inflammation in both the synovium and ankle joint. They also were both effective in improving bone loss, microarchitecture, and overall bone quality. TBD reduced the expression of MMP13, IL-17, and p-JNK protein in the synovium of CIA rats. ICA, which was screened, suppressed TNF-α or LPS-triggered inflammatory responses via down-regulating IL-17 signaling, involving in MMP13, IL-1ß, IL-23, and IL-17, and the MAPK pathway including p-ERK, p-JNK, and p-P38, both in MH7A cells and in RAW264.7 cells. Furthermore, ICA prevented osteoclasts from differentiating and bone resoprtion in a dose-dependent manner in vitro. CONCLUSION: This study provides the first evidence that TBD exerts intervening effects on RA-induced OP, possibly through the downregulation of the IL-17/MAPK signaling pathway by ICA. The findings of our study provides valuable insights for further research in this area.

Artemisiae Argyi Folium is commonly used in clinical practice. Artemisiae Verlotori Folium, the dried leaves of Artemisia verlotorum, is often used as a folk substitute for Artemisiae Argyi Folium in Lingnan area. In this study, gas chromatography-triple quadrupole mass spectrometry(GC-MS) was used to detect the volatile oil components of 27 samples of Artemisiae Verlotori Folium and 13 samples of Artemisiae Argyi Folium, and the volatile components were compared between the two species. The internal standard method was combined with multi-reaction monitoring mode(MRM) to determine the content of six major volatile components. Hierarchical clustering analysis(HCA) and orthogonal partial least squares-discriminant analysis(OPLS-DA) were carried out for the content data. The results showed that the Artemisiae Argyi Folium samples had higher content and more abundant volatile oils than the Artemisiae Verlotori Folium samples. Artemisiae Argyi Folium mainly had the components with lower boiling points, while Artemisiae Verlotori Folium mainly had the components with higher boiling points. Terpenoids were the main volatile components in Artemisiae Verlotori Folium(mainly sesquiterpenoids) and Artemisiae Argyi Folium(monoterpenoids). In addition, Artemisiae Argyi Folium had higher content of oxygen-containing derivatives than Artemisiae Verlotori Folium. Furthermore, the stoichiometric analysis showed that the two species could be distinguished by both HCA and OPLS-DA, indicating that the volatile components of the two were significantly different. This study can provide a scientific basis for the quality evaluation and data support for the local rational application of Artemisiae Verlotori Folium in Lingnan.

The moistening process of Rehmanniae Radix was characterized quantitatively by moisture phase, texture properties, and component content based on water absorption kinetics and expansion kinetics. Non-linear fitting of water absorption kinetics and expansion kinetics in the moistening process of Rehmanniae Radix was carried out. Low-field nuclear magnetic resonance and imaging(LF-NMR/MRI) technology was used to investigate the phase state and distribution changes of water during the moistening process. The Texture Analyzer was used for the determination of texture properties. The correlations between water absorption rate, expansion rate, water phase state, hardness, and compression cycle work of Rehmanniae Radix at different moistening time were analyzed. The results showed that the water absorption kinetics and expansion kinetics of Rehmanniae Radix were in accordance with the first-order kinetics. Moreover, the water absorption rate and expansion rate increased with the increase in temperature but decreased with the increase in the size of the medicinal materials.In the moistening process, the moisture was transferred from the outside to the inside, and the proportion of the moisture phase changed significantly.Within 16 hours, free water increased from 0.825% to 97.7%,while bound water decreased from 99.2% to 2.33%.Within 28 hours, the texture properties, such as hardness and compression cycle work, decreased gradually with the prolongation in moistening time.At 32 hours, water was evenly distributed throughout the whole medicinal material, and the texture properties also tended to be stable.Pearson correlation bivariate analysis showed that moistening time, water absorption rate, expansion rate, the relative content of free water and bound water, hardness, and compression cycle work were significantly correlated, suggesting that water absorption kinetics and expansion kinetics, LF-NMR/MRI,and Texture Analyzer could directly and quantitatively characterize the moistening process.This study is expected to provide a scientific basis for clarifying the scientific connotation of the moistening process of Rehmanniae Radix.

Schizonepetae Herba and Schizonepetae Spica are well-known Chinese herbal medicines for wind dispersing and exterior releasing. Through textual research on Schizonepetae Herba and Schizonepetae Spica, the discrimination of their medicinal parts in history was clarified, and the processing, the property(nature and flavor), meridian tropism, functions, indications, usage, dosage, and the selection of decoction pieces were compared to provide the basis for clinical application. As a result, the whole herb of Schizonepeta tenuifolia was used as medicine in the early records. The aerial part and the dried spike of S. tenuifolia were used as medicines separately in the Song Dynasty, which was recorded in the Atlas of Materia Medica(Ben Cao Tu Jing). Some ancient classics emphasized that only the dried spike could be used as medicine. The separation of Schizonepetae Herba and Schizonepetae Spica meets the different needs of clinical medication and supports the concept of rational development and utilization of Chinese medicine resources. About ten processing methods for Schizonepetae Herba and Schizonepetae Spica have been recorded since ancient times, and raw and charred drugs were the major products. Raw Schizonepetae Herba is required to be used in sections, whereas raw Schizonepetae Spica in clean preparation. Both charred products should avoid scorching. Schizonepetae Herba and Schizonepetae Spica are similar in the property(pungent, bitter, and warm), meridian tropism(lung and liver meridians, as well as qi and blood aspects), and functions(releasing exterior, dispersing wind, regulating and stopping blood, promoting eruption, dispelling sores, promoting digestion, eliminating alcohol effect, etc.), but Schizonepetae Spica is superior in efficacy. For Schizonepetae Herba and Schizonepetae Spica in traditional Chinese medicinal prescriptions, the raw and charred products are similar in usage and dosage, while their focuses in clinical compatibility vary. The raw and charred products of Schizonepetae Herba and Schizonepetae Spica are widely applied clinically. Decoction pieces of different specifications can result in different efficacies and clinical applications, so medication should be performed with caution.

Liangmianzhen(Zanthoxyli Radix) has long been used as medicine. The current medicinal parts are different from those in the ancient. As recorded in the Chinese Pharmacopeia, the medicinal part is root. However, in ancient works, the medicinal parts include root, stem, leaf, and fruit. In an attempt to find the historical basis that stem is a reasonable medicinal part, the herbalogical study was carried out on this medicinal based on the formal names, synonyms, original plant, medicinal parts, habitat of the medicinal plant, producing area, processing and preparation methods, efficacy, and indications recorded in ancient Chinese materia medica and local gazetteers. The results showed that Liangmianzhen was firstly recorded as a medicinal in Shennong's Classic of Materia Medica with the formal name of "Manjiao". "Manjiao" was adopted from the Han Dynasty to the Qing Dynasty when it was changed to "Rudijinniu", the name originating from the folk in the south of the Five Ridges. Now, the formal name is "Liangmianzhen", which was firstly recorded in Wuxuan County Gazetteer in 1914 and then as a synonym in the Updated Records of Picking Herbs in the South of the Five Ridges. According to the formal names, synonyms, and the descriptions of the original plant, the medicinal plants of Liang-mianzhen have the characteristics of shrub-like young seedlings, vine adult seedlings, corymbiform thyrsus, stems with thorns, amphitropous golden-yellow roots with horn-like branches, and thorns on both sides of the leaves. Thus, "Manjiao", "Rudijinniu", and "Liangmianzhen" were from the same species of Zanthoxylum nitidum(Rutaceae), which was also verified based on the growth environment, habitat, processing and preparation methods, efficacy, and indications. In ancient times, the stem and root were the main medicinal parts and leaves and fruits were also used. However, in the Chinese Pharmacopeia, root is recorded as the only medicinal part, which is obviously inconsistent with the records in the ancient classics. In light of the limited medicinal resources for Liang-mianzhen, other medicinal parts of Z. nitidum is recommended. This study clarified the medicinal parts of Z. nitidum in history. It is recommended that the stem be added to the medicinal parts of Z. nitidum in the next edition of Chinese Pharmacopeia.

In ancient times, the original plants of Citri Exocarpium Rubrum and Citri Grandis Exocarpium had experienced succession and change, including tangerine(Citrus reticulata), pomelo(C. grandis), and Huazhou pomelo(C. grandis 'Tomentosa'), a specific cultivar of C. grandis produced in Huazhou, Guangdong. Before the Qing Dynasty, tangerine was the main original plant, while Huazhou pomelo came to the fore in the Qing Dynasty. In the 1950 s and 1960 s, the producing area of Huazhou pomelo was destroyed, and thus it had to be supplemented with pomelo. From then on, C. grandis 'Tomentosa' and C. grandis were both listed as the original plants of Citri Grandis Exocarpium in the Chinese Pharmacopoeia. This paper reviewed the historical evolution of the collection, processing, and efficacy of Citri Exocarpium Rubrum and Citri Grandis Exocarpium. The research showed that:(1)The harvest time of the original plants of Citri Grandis Exocarpium and Citri Grandis Exocarpium had changed from maturity to immaturity. The collection and processing of Citri Exocarpium Rubrum was first recorded in the Illustrated Classics of Materia Medica in the Song Dynasty. During the Ming and Qing Dynasties, the mesocarp of Citri Exocarpium Rubrum needed to be removed completely, and Citri Grandis Exocarpium from C. grandis 'Tomentosa' was processed into different specifications such as seven-piece, five-piece, and single piece. Furthermore, processed young fruits of Huazhou pomelo appeared.(2)Citri Exocarpium Rubrum and Citri Grandis Exocarpium were processed with carp skin for the first time in the Master Lei's Discourse on Medicinal Processing. It was suggested that carp skin might be helpful for eliminating bones stuck in throat. During the Song, Jin, and Yuan Dynasties, some other processing methods such as ba-king, stir-frying, and salt-processing appeared. Honey, soil, ginger juice, and alum were firstly used as adjuvants for the processing in the Ming and Qing Dynasties. Citri Exocarpium Rubrum was mainly prepared with salt in order to improve the effect of lowering Qi, while it was unnecessary for Citri Grandis Exocarpium from C. grandis 'Tomentosa' because of its obvious effect of lowering Qi and eliminating phlegm. The stir-frying and honey-frying methods helped reduce the strong effect of Citri Grandis Exocarpium from C. grandis 'Tomentosa'.(3)According to the application of Citri Exocarpium Rubrum and Citri Grandis Exocarpium in history, their medicinal use began in Han and Tang Dynasties, developed in Song, Jin, and Yuan Dynasties, and matured in Ming and Qing Dynasties. Citri Grandis Exocarpium from C. grandis 'Tomentosa' was originally applied in Ming and Qing Dynasties, and it still plays an important in role treating COVID-19 nowadays. Moreover, Citri Grandis Exocarpium from C. grandis had cold medicinal property, while Citri Grandis Exocarpium from C. grandis 'Tomentosa' had warm medicinal property, and thus they should not be treated the same. At present, Huazhou pomelo has a certain production scale. Therefore, it is recommended that in the next edition of Chinese Pharmacopoeia, only C. grandis 'Tomentosa' should be included as the original plant of Citri Grandis Exocarpium, and C. grandis should be deleted. The results are conducive to the further development and utilization of Citri Exocarpium Rubrum and Citri Grandis Exocarpium, and support the rational use of Citri Grandis Exocarpium and its processed products.

Tianxiong has been used as a Chinese medicinal in China for thousands of years, and the earliest record can be traced back to the Shennong's Classic of Materia Medica. It is effective in dispersing wind, dissipating cold, and replenishing fire to streng-then yang. To clarify the origin of Tianxiong, the present herbalogical study reviewed the ancient and modern literature from the origin, processing, and clinical efficacy. Before the Tang Dynasty, although the description of Tianxiong was quite superficial, an apparent difference between Tianxiong and Fuzi was recognized. In the Tang and Song Dynasties, Tianxiong and Fuzi were mistakenly recognized to be prepared from a same plant since their raw materials came from artificial cultivation. Medical literature in the Ming and Qing Dynasties mostly followed the previous records, with the origin of Tianxiong remaining controversial. There were three mainstream views about the origin of Tianxiong according the ancient medical books. First, Tianxiong was a kind of Aconiti Radix(Chuanwu) without attachment of Fuzi. Second, Tianxiong was the large Fuzi. Third, Tianxiong derived from Aconiti Kusnezoffii Radix(Caowu) about 10 cm in length. By contrast, Fuzi in a large size was simply regarded as Tianxiong in modern times. The processing methods were diversified in the ancient times, and the fire-processing was continuously applied. With the deepening of the research on the efficacy and detoxification mechanism, more methods were discovered, such as processing with ginger juice, child's urine and alcohol. As for modern times, the processing of Tianxiong has not been nearly passed down. The characteristic processing of Tianxiong only handed down in Sichuan province and Lingnan area, which can be discriminated by the last step. The efficacies of Tianxiong can be directly understood from its literal name, including dispersing wind, dissipating cold, and replenishing fire to assist yang. Nowadays, Tianxiong is mostly used to strengthen yang.

In ancient times, there were two types of "Juhong" came from the tangerines(Citrus reticulata) and the pomelos(C. grandis and its cultivars), which corresponded to Juhong and Huajuhong recorded in the Chinese Pharmacopoeia respectively. In different periods, Juhong basically came from the same species and the same medicinal parts, but there were also some differences. This article sorted out the ancient and modern literature, under the guidance of "Succession theory of Medicinal materials varieties" and "Change theory of Medicinal materials varieties"(XIE Zong-wan), and combined with field investigation, the evolution and reasons of the original plants and medicinal parts of Juhong were analyzed. In the Han Dynasty and before, the peel of tangerines and pomelos were both used as medicine. In the Southern and Northern Dynasties, the way tangerine peel was used was dried and aged, and then "soaked in hot water and scraped off the mesocarp", which had the essence of only using exocarp as medicine of Juhong already, and its original plant was C. reticalata. In the Song Dynasty, the name of "Juhong" and its medicinal usage were recorded in book on materia medica, and the species and medicinal parts of tangerine were inherited from the previous dynasties. The way tangerine peel was used was only dried and aged without removing the mesocarp. The medicinal material obtained by the way was called Chenpi(dried and aged tangerine peel). The item "Juhong" listing as a separate medicinal material was first recorded in the Collected Discussions from Materia Medica(Bencao Huiyan) in the Ming Dynasty. In the Ming Dynasty, the Dao-di habitat of Juhong was recorded as Guangdong province in most books on materia medica, and the original plants probably were C. reticalata and C. grandis 'Tomentosa'(Huazhou pomelo, a special cultivated species of C. grandis produced in Huazhou, Guangdong, which was recorded in the Chinese Pharmacopoeia as "Huajuhong"), according to the records in the local chronicles. During the Qing Dynasty and the Republic of China, the original plants of Juhong were C. reticalata and C. grandis 'Tomentosa'. Of the two, the latter one was considered as the better. As far the medicinal part, it was still the exocarp, while the whole young fruit of C. grandis 'Tomentosa' began to be used as medicine. After the founding of The People's Republic of China, the exocarps of Citrus reticalata, C. grandis and C. grandis 'Tomentosa' were listed in the Chinese Pharmacopoeia under "Juhong". From the Northern and Southern Dynasties to the Republic of China, C. grandis exocarp was a fake of Juhong. Therefore, it was contradictory to historical records that C. grandis exocarp was listed in the Chinese Pharmacopoeia as Huajuhong. Juhong had been divided into two types as "Juhong" and "Huajuhong" since 1985. The medicinal part of Huajuhong was only the exocarp of immature and nearly mature fruits, but not the whole young fruit, the actual mainstream medicinal part of Huajuhong. The results are helpful to clarify the historical evolution of species and medicinal parts of Juhong and Huajuhong. It is suggested that in the next edition of Chinese Pharmacopoeia, only C. grandis 'Tomentosa' should be included as the original plant of Huajuhong, and C. grandis should be deleted, and the young fruit should be added in the medicinal parts besides the exocarp of immature and nearly mature fruit.

Citri Sarcodactylis Fructus is a both medicinal and edible species specified by the China Ministry of Health, with a long history in China. According to the ancient monographs about materia medica, it was found that the records of the Citri Sarcodactylis Fructus on the original plants were confused. This paper reviewed the ancient monographs about materia medica, and made a summarization and textual research on the name, origin, habitat, processing methods, medicinal properties and clinicacy efficacy of Citri Sarcodactylis Fructus based the comprehensive analysis on modern literatures and authoritative books of Chinese herbal medicine. The results indicated that there were many bynames of Citri Sarcodactylis Fructus. Before the Yuan Dynasty, there was a mixed use of Citri Sarcodactylis Fructus and Citri Fructus, which were not distinguished from each other in terms of nature and taste until the Yuan dynasty. Citri Sarcodactylis Fructus was a varietas of Citri Fructus. The main shape of the original plant of Citri Sarcodactylis Fructus is "like a human hand with fingers" as recorded in ancient monographs about materia medica. The main places of origin of Citri Sarcodactylis Fructus were Guangdong, Zhejiang, Fujian, Sichuan, which were relatively stable. There were fewer records about medicinal proces-sing methods of Citri Sarcodactylis Fructus. Only steaming and baking methods were found in ancient monographs about materia medica, and the steaming method could reduce the irritability of Citri Sarcodactylis Fructus. The processing of therapeutic dietary of Citri Sarcodactylis Fructus was widely used in folk, which was represented by Chaozhou Laoxianghuang, a traditional succade made of Citri Sarcodactylis Fructus. According to the 2015 edition of Chinese Pharmacopoeia, Citri Sarcodactylis Fructus had effects in soothing liver and regulating gas, relieving pain in the stomach, eliminating dampness and resolving phlegm, which was basically consistent with the descriptions in ancient monographs about materia medica. This paper defined the original plant of Citri Sarcodactylis Fructus, and sorted out and summarized the processing methods, nature and taste of Citri Sarcodactylis Fructus, so as to provide data support for the standardization of the processing technology and the development and utilization of Citri Sarcodactylis Fructus.

Coicis Semen is widely used as a raw material which can be used as both medicine and food among people. According to the ancient monographs on materia medica and relevant documents on the processing specifications in various provinces and cities, herba logical study on the historical evolution of the processing methods of Coicis Semen was conducted in this paper from the aspects of collecting and processing methods of Coicis Semen, the processing methods in the past dynasties and the nature, flavour and efficacy of Coicis Semen. The results showed that the processing methods of Coicis Semen recorded in monographs on materia medica mainly included stir-frying, glutinous rice stir-frying, salt processing(including salt cooking and salt stir-frying), stir-frying with the earth scraped from the wall facing east, and ginger juice stir-frying, etc. Among them, stir-frying, and stir-frying with the earth scraped from the wall facing east are still used nowadays. The bran stir-frying is the improved version of glutinous rice stir-frying in order to be adaptive to the modern-day situation and the needs of the present. In addition, the ancient shell removal and kernel keeping method are also included in the processing procedures in modern local processing specifications, which are combined with frying to form a new method named "Fazhi" processing( "Fazhi" means a processing method of multiple procedures). The 2015 edition of Chinese Pharmacopoeia records that Coicis Semen is helpful to clear dampness and promote diuresis, strengthen the spleen and prevent diarrhea, eliminate impediment, discharge pus, resolve toxin and a mass, etc., which are consistent with those contained in ancient monographs on materia medica. After the "Fazhi" processing, the cold nature of Coicis Semen has been removed and its nature,flavour and meridian tropism have been changed, so its application scopes expanded. The results of this study clearly traced the history of the collecting and proces-sing of Coicis Semen, summarized the nature, flavour and efficacy of Coicis Semen contained in both ancient and modern literature, and provided a historical basis for the standardization of the subsequent processing technology of Coicis Semen, the clinical application of various processed products, and the further development and utilization of medicinal materials.

Colla Corii Asini(Ejiao)is an important Chinese medicine used in China for thousands of years, and is well known for its famous tonic properties. The herbalogical study was detailed carried out based on the naming, habitat, harvesting, processing, medicinal properties and clinical efficacy. The results showed that the name of Ejiao could be traced back to Shennong's Materia Medica, and various names of Lvpi Jiao, Penfu Jiao and Fuzhi Jiao were recorded in other ancient books. In the many intervening centuries, the main materials of Ejiao had been replaced from cow leather before Tang Dynasty to donkey skin in the middle to late Tang Dynasty. This phenomenon could be probably caused by complicated social factors of various periods and different efficacy of Ejiao made by all kinds of raw materials. Ejiao was merely processed with the simple methods before Tang Dynasty, which subsequently improved avariety of methods to enhance the supplementation action. Most importantly, Ejiao has a wide clinic application along with the development of processing theories and methods, which can be found in various Classics, especially in imperial medical case record in Qing Dynasty.

Cervi Colla, deer's gelatin, had two kinds of original sources historically, including the skin and antler of deer, known as Cervi Corii Colla(Lupijiao, LPJ) and Cervi Cornus Colla(Lujiaojiao, LJJ) respectively.LJJ is the mainstream of the market, while LPJ is only used by common people in Guizhou and Jilin etc. This article sorted out the ancient and modern literature(since Rites of the Zhou in Zhou Dynasty) on Cervi Colla and conducted the herbalogical study. The results of the study include:â In ancient China, there were six types of commonly-used Colla derived from six animals, including deer, horse, cow, rat, fish and rhinoceros. Cervi Colla was ranked the most top among them, and it was often used as adhesive to make bow and Chinese inksticks and more commonly used as a medicine.Cervi Cornus Colla was first described as a medicinal by the name "Bai Jiao"(white gelatin)in The Divine Husbandman's Classic of Material Medica(Shen Nong Ben Cao Jing).â¡ Initially, both the skin and antler were used as raw materials to make Cervi Colla, but antler became the only raw material, and deer skin disappeared from the mainstream of raw materials for Cervi Colla. This can be attributed to other diverse and luxurious uses of the skin, such as making dress and hats, etc., and the easy accessibility of deer antlers. ⢠The sources of Cervi Colla were not limited to Cervus elaphus(red deer) or C. nippon(sika deer), and it also included animal from the family Cervidae, such as Elaphurus davidianus(elk) and C. unicolor(sambar). ⣠The processing method was passed down from ancient times to the present, and no significant changes had occurred. ⤠LPJ and LJJ had many similar effects, and their nature was both warm. The effect of LJJ was to warm the liver and kidney, replenish vital essence and blood, and to reinforce Yang. While the effect of LPJ was to reinforce both Yin and Yang, replenish blood, and stop bleeding. It has a unique advantage for both reinforcing Yin and Yang. The findings of this paper can provide support for the promotion of LPJ and the development of its medicinal value.

In this study, we aim to determine the chemical constituents of six Chinese medicinal materials from the Citrus genus using high-performance liquid chromatography and high-resolution mass spectrometry. Eight flavonoids and one coumarin were identified and further quantified as marker substances by high-performance liquid chromatography method. The separation was performed on an Agilent TC-C18 column with 0.1% formic acid and acetonitrile as the mobile phase under gradient elution. The analytical method was fully validated in terms of linearity, sensitivity, intra- and inter-day precision and repeatability, limit of detection, limit of quantitation, and recovery. It was subsequently applied to evaluate the quality of 103 batches of the Chinese medicinal materials from the Citrus genus. In addition, the principal constituent analysis was used to compare the samples of different species from the Citrus genus leading to successful classification of the samples in accordance with their origins. It was found that the contents of nine constituents varied greatly in different ripening stages and varieties of the samples from the Citrus genus. In addition, neoeriocitrin and 5,7-dimethoxycoumarin were determined as two unique constituents of 'Zhiqiao' and 'Foshou', respectively. In conclusion, this study provides a chemical basis for quality control of Chinese medicinal materials from the Citrus genus.

As a most important Chinese materia medica, Aconiti Lateralis Radix Praeparata(Fuzi) had been widely used in China for thousands of years. This herbalogical study was systematically performed based on variation characteristics of the naming, habitat, harvesting, processing and properties. The sharp toxicity of Fuzi had been well known since the spring and autumn period in the history, which was much earlier than that its medical properties was understood and applied. Sichuan province was regarded as the geo-authentic region of Fuzi all along, where the best quality goods could be provided for clinic use. The study showed the harvesting time of Fuzi was changing in different periods, and the possible effects were of climate change and artificial planting. The perishable characteris-tics of Fuzi severely limited its storage period; therefore, different kinds of storage methods were effectively used since Tang Dynasty. For thousands of years, Fuzi had been processed with various accessories to reduce toxicity, while simultaneously the study on processing mechanism was on going all the time. Fuzi was widely used in clinical practice to cure Yang depletion syndrome, which was based on its function of enhancing Yang and removing cold. Along with the further study on quality evaluation standard, Fuzi will probably get a much wider range of applications.

Chinese medicine is the traditional treasure of China nation. As the basis of Chinese medicine, traditional Chinese medicine(TCM) plays an important part for the development of Chinese medicine. Genuine medicinal materials with special characteristics of TCM growing in special ecological environment, is recognized as the high quality medicine. Research on genuineness evaluation of TCM is the key to ensure its clinical applications, efficacy and the process of modernization and internationalization for Chinese medicine. Lingnan region of China is situated in the tropical and subtropical zones, where there are rich geothermal and hydrothermal resources. The superior natural and geographic environment of Lingnan has given birth to a variety of native herbal drugs. And treating and preventing diseases with Lingnan herbal drugs has a long story. This study mainly evaluated the genuineness of Lingnan herbal drugs from the aspects of ecological factor, thegenetic information, the history, the culture, the clinical efficacy and the processing, and proposed a new idea to investigate the genuineness of TCM, aiming to provide a scientific basis for genuineness evaluation.

Poliumoside is representative of phenylethanoid glycosides, which are widely found in many plants. Poliumoside is also regarded as the main active component of Callicarpa kwangtungensis Chun (CK), though its oral bioavailability in rat is extremely low (0.69%) and its in vivo and in vitro metabolism has not yet been systematically investigated. In the present study, an ultra performance liquid chromatography/quadrupole time-of-flight mass spectrometry (UPLC/Q-TOF-MS) method was employed to identify the metabolites and investigate the metabolic pathways of poliumoside in rat after oral administration 1.5 g·kg-1 of poliumoside. As a result, a total of 34 metabolites (30 from urine, 17 from plasma, and 4 from bile) and 9 possible metabolic pathways (rearrangment, reduction, hydration, hydrolyzation, dehydration, methylation, hydroxylation, acetylation, and sulfation) were proposed in vivo. The main metabolite, acteoside, was quantified after incubated with rat intestinal bacteria in vitro. In conclusion, the present study systematically explored the metabolites of poliumoside in vivo and in vitro, proposing metabolic pathways that may be significant for further metabolic studies of poliumoside.

In the folk medicine, it was believed that the raw Sanqi could remove blood stasis, swelling and pain, while the cooked Sanqi could replenish blood. This article began with the first record of Sanqi in ancient herbal medicine literature, and the nature, flavor and efficacy of Sanqi, then listed the processing methods and usage of Sanqi recorded in ancient herbal medicine literature, and compared with the modern processing methods. The results showed that the processing methods of raw Sanqi included making powder, chewing, vinegar grinding and wine grinding, in which the method of making powder was still in use, and there were particle size requirements on the Sanqi powder listed in most modern preparation specifications. The processing methods of cooked Sanqi included baking, frying and steaming, in which the method of steaming was still in use, but had some changes. The new processing method was frying with edible oil. The results clarify the history of the processing of Sanqi, and provide a reference for the research and application of the processing methods of raw and cooked Sanqi.
