To explore the suitable fertilizing pattern for Saposhnikovia divaricata in the genuine producing area, a field trial was carried out to investigate the changes in the yield and quality of medicinal materials and soil in different fertilization patterns, such as organic fertilizer substitution(organic fertilizer+NPK fertilizer) and chemical fertilizer reduction(organic fertilizer+NPK fertilizer decrement and organic fertilizer+NPK fertilizer decrement+soil conditioner). The comprehensive analysis of all treatments was based on the medicine quality evaluation data set and soil quality evaluation data set, respectively, by CRITIC weight method. The results showed that(1) the yield of S. divaricate increased by 4.93%-12.67% under the organic fertilizer substitution mode, and the yield increased by 44.43% under the treatment of chemical fertilizer reduction YHT15, which was higher than that of the organic fertilizer substitution mode.(2) The quality of S. divaricate under the two fertilization modes was superior to the standard in the Chinese Pharmacopoeia, and the application of biochar was helpful to improve the quality of S. divaricate quality, with an increase of 82.83%-181.54%. CRITIC method analysis showed that fertilization treatments with high comprehensive scores were YHT15, YH30, and YH15.(3) Soil quality under the two fertilization modes was higher than that under the control. The fertilization treatments with higher comprehensive scores of soil quality were YHT15, YHT30, and YHT. The fertilization mode of adding biochar as soil conditioner, applying an appropriate amount of organic fertilizer, and reducing part of chemical fertilizer is the appropriate way to develop ecological plantation of S. divaricata in the Baicheng area in the western Jilin province. The specific fertilization mode is as follows. The basic fertilizer was 361 kg·hm~(-2) superphosphate+110 kg·hm~(-2) potassium sulfate+82 kg·hm~(-2) organic fertilizer+10 000 kg·hm~(-2) rice husk biochar, and urea was applied as top fertilizer three times, 29, 29, and 20 kg·hm~(-2), respectively.

Advances in Phytochemistry and Modern Pharmacology of Saposhnikovia Divaricata (Turcz.) Schischk / 中国结合医学杂志

Saposhnikovia divaricata (Turcz.) Schischk (S. divaricata, Fangfeng) is a herb in the Apiaceae family, and its root has been used since the Western Han Dynasty (202 B.C.). Chromones and coumarins are the pharmacologically active substances in S. divaricata. Modern phytochemical and pharmacological studies have demonstrated their antipyretic, analgesic, anti-inflammatory, antioxidant, anti-tumor, and anticoagulant activities. Technological and analytical strategy theory advancements have yielded novel results; however, most investigations have been limited to the main active substances-chromones and coumarins. Hence, we reviewed studies related to the chemical composition and pharmacological activity of S. divaricata, analyzed the developing trends and challenges, and proposed that research should focus on components' synergistic effects. We also suggested that, the structure-effect relationship should be prioritized in advanced research.

Effects of growth patterns and years on quality of Saposhnikoviae Radix samples / 中国中药杂志

This study aims to reveal the effects of different growth patterns and years on the quality of Saposhnikoviae Radix samples. The apparent colors of the powder samples were quantified by a colorimeter, and the total color values(E~*ab) were calculated. The content of prim-O-glucosylcimifugin, cimifugin, 4'-O-β-D-glucosyl-5-O-methylvisamminol, sec-O-glucosylhamaudol, and 3'-O-angeloylhamaudol in the samples was simultaneously determined by high performance liquid chromatography(HPLC). Cluster analysis, principal component analysis, partial least squares discriminant analysis, and Pearson correlation analysis were performed to analyze the powder chromatic values and the content of 5 components. The results showed that the E~*ab values of the samples were in the order of wild group<multiple-year-old group<one-year-old group. The content of cimifugin, sec-O-glucosylhamaudol, and 3'-O-angeloylhamaudol in the wild group was significantly higher than that in the multiple-year-old and one-year-old groups. The results of multivariate statistical analysis showed that the quality of multiple-year-old group varied greatly. The quality of the multiple-year-old samples was close to that of the wild group and better than that of the one-year-old group. The variable importance in the projection(VIP) values of b~*, 3'-O-angeloylhamaudol content, E~*ab, and L~* were all larger than 1, and that of cimifugin content was close to 1. The E~*ab value was negatively correlated with the content of prim-O-glucosylcimifugin, cimifugin, sec-O-glucosylhamaudol, and 3'-O-angeloylhamaudol, while it had no linear correlation with the 4'-O-β-D-glucosyl-5-O-methylvisamminol content. The growth patterns and years had different effects on the quality of Saposhnikoviae Radix samples. The chromatic values of Saposhnikoviae Radix and the content of 5 components can be used to evaluate the quality of Saposhnikoviae Radix, and 3'-O-angeloylhamaudol and cinmifugin can be considered as markers for the quality control of Saposhnikovia divaricata during the growing process.

Quality evaluation of Saposhnikoviae Radix based on QAMS combined with information entropy-response surface method / 中国中药杂志

This research was used with high performance liquid chromatography(HPLC), combined with information entropy-response surface method(RSM) to investigate the ethanol concentration, extraction time, liquid-to-material ratio. Taking the content of four chromogens as evaluation indexes, the weight coefficients of each index were given, and the comprehensive score was calculated to optimize the extraction process. Then, prim-O-glucosylcimifugin was used as the reference, the relative calibration factors(RCFs) of cimifugin, 4'-O-β-D-glucosyl-5-O-methylvisamminol and sec-O-glucosylhamaudo to prim-O-glucosylcimifugin were calculated respectively. The contents of four components in Saposhnikoviae Radix were determined by both external standard method(ESM)and quantitative analysis of multi-components by single marker(QAMS) method, and the results were compared. At last, combined with principal component analysis(PCA) and orthogonal partial least squares discriminant analysis(OPLS-DA) to evaluate the quality of the Saposhnikoviae Radix in different production areas. The optimal extraction process parameter of the Saposhnikoviae Radix was as follows: liquid-to-material ratio is 60∶1(mL·g~(-1)), extraction time is 35 min, and ethanol concentration is 70%. The repeatability of the RCFs was perfect, and the results calculated by the QAMS were consistent with the results from the ESM. The stoichiometric results indicate that there are obvious differences in the distribution of Saposhnikoviae Radix in different production areas, and cimifugin and prim-O-glucosylcimifugin are the characteristic compounds that cause this difference. In this study, the optimal extraction process is stable and feasible, and the method of QAMS is accurate and reliable. From the perspective of four chromogens, there are differences in the quality of the Saposhnikoviae Radix in different production areas. Therefore, the established extraction process combined with the method of QAMS can be used to evaluate the quality of Saposhnikoviae Radix and provide a scientific basis for the quality control of Saposhnikoviae Radix.

The calibration of chromone reference extract(CRE) was conducted and a quality control method of Saposhnikoviae Radix(SR) was established based on CRE. Meanwhile, the quality control system of SR was improved and the feasibility of using reference extract as a substitute for single reference substance in quality control of Chinese medicine was discussed. In this study, the content of the prepared CRE was calibrated with prim-O-glucosylcimifugin, cimifugin, 4'-O-β-D-glucosyl-5-O-methylvisamminol, and secO-glucosylhamaudol as indicators. Subsequently, an HPLC analytical method was developed to determine the content of four chromones in 20 batches of SR samples based on the CRE with known content as the standard substance. T-test was used for the comparison of the determination results of the two methods(single chemical component and CRE as reference substances, respectively), and the P values of prim-O-glucosylcimifugin, cimifugin, 4'-O-β-D-glucosyl-5-O-methylvisamminol, and sec-O-glucosylhamaudol were 0. 16,0. 39, 0. 14, and 0. 42. The results demonstrated that there was no significant difference between the two methods. This study initially verified the feasibility that the CRE could be used as a substitute for single reference substance in quality control of SR. In conclusion,this study is expected to provide a scientific basis and a new research model for the application of reference extract in the quality control of Chinese medicine.

Comparison of soil hydraulic properties in wild and cultivated areas of Notopterygium incisum / 中国中药杂志

To clarify the difference of soil moisture characteristics between mixed broad leaf-conifer forest soil and artificial cultivation of Notopterygium incisum, the HYPROP system and the dew point potential meter were used to determine soil water retention curves(SWRC) for samples of two horizons(i.e. 2-7 cm, 10-15 cm). The basic physical and chemical properties of soil and its water characteristic parameters were also determined. The result showed as fllows:①The bulk density of mixed coniferous-broad leaf forest soil was between 0.33 and 0.52 g·cm~(-3), significantly lower than the corresponding value of field soil(1.01-1.18 g·cm~(-3))(P<0.05), While the organic matter content was significantly higher than the corresponding value of field soil(P<0.05). ②The saturated water content(θ_s), field water holding capacity(θ_(FC)) and Water that can be effectively utilized by plants(θ_(PAC)) of mixed coniferous-broadleaved forest soil were significantly higher than the corresponding value of field soil(P<0.05), while the retained water content(θ_r) value that cannot be effectively utilized by plants was significantly lower than that of field soil(P<0.05). ③The values of structural porosity(0.13-0.24 cm~3·cm~(-3)) and Matrix porosity(0.34-0.44 cm~3·cm~(-3)) of mixed coniferous-broadleaved forest soil were higher than the corresponding values of field soil. Therefore, with low bulk density and high content of organic matter, mixed coniferous-broadleaved forest soil can store more water in soil in the form of effective water to meet the needs of plants for water, thus possibly forming high quality medicinal materials of Notopterygii Rhizoma et Radix. In conclusion, the results of this study can provide theoretical basis guidance for soil structure improvement and water management to form high quality medicinal materials in the artificial cultivation of N. incisum.

The aim of this paper was to investigate the effect of Schizonepetae Herba and Saposhnikoviae Radix(wind medicine) on the expression of AQP4 and AQP8 in colonic mucosa in rats with ulcerative colitis(UC). A total of 35 healthy SD male rats were randomly divided into normal group(gavaged with normal saline), DSS model group, as well as low, middle, and high dose wind medicine groups(Schizonepeta and Saposhnikovia 1∶1, gavaged at dosages of 6, 12, and 24 g·kg~(-1)·d~(-1)), with 7 in each group. UC rat model was established by free drinking of 3% dextran sulphate sodium(DSS) solution for 10 days. At the end of the 10 th day after the treatment, mice were put to death to collect colonic mucosa. The length of colon was measured; the colonic mucosal injury index(CMDI) and pathological changes of colon were observed. ELISA method was used for measuring the content of serum IL-1, IL-8, and immunohistochemical method was used to measure AQP4, AQP8 protein expressions in colon mucosa. The expressions of AQP4, AQP8 mRNA were measured by Real-time PCR. As compared with the normal group, the length of colon tissue was significantly reduced(P<0.01), CMDI scores and pathological scores were significantly increased(P<0.01), the levels of serum IL-1 and IL-8 were significantly increased(P<0.05) in model group; the immunohistochemical results showed that the protein expressions of AQP4, AQP8 were lower; the color was light yellow or brown; AQP4, AQP8 mRNA expressions in colon mucosa were significantly decreased in model group(P<0.01). CMDI scores, pathological scores, and the levels of serum IL-1, IL-8 in high, middle, low dose wind medicine groups were obvious lower than those in the model group(P<0.01 or P<0.05); the protein expressions of AQP4, AQP8 were higher; the color was chocolate brown or dark brown; the length of colon tissue, and the expressions of AQP4, AQP8 mRNA were obvious higher in wind medicine groups(P<0.01 or P<0.05). Schizonepetae Herba and Saposhnikoviae Radix could significantly improve the symptoms and histopathology of UC model rats and accelerate the intestinal mucosal healing. The mechanism may be related with up-regulating the expression level of AQP4 and AQP8 in colonic mucosa.

The anticonvulsant effects of Ducrosia anethifolia (Boiss) essential oil are produced by its main component alpha-pinene in rats / Os efeitos anticonvulsivantes do óleo essencial de Ducrosia anethifolia (Boiss) são realizados pelo seu principal componente alfa-pineno em ratos

ABSTRACT Ducrosia anethifolia has been recommended as a remedy for neurological disorders. However, the anticonvulsant effects of D. anethifolia essential oil (DAEO) and its major constituent α-pinene have not yet been clarified. Methods: A rat model of pentylenetetrazole (PTZ)-induced convulsions was used. Oxidant and antioxidant parameters were assayed in the temporal lobe. Results: The data showed that DAEO (50, 100 and 200 mg/kg, i.p.) and α-pinene (0.2 and 0.4 mg/kg i.p.) delayed the initiation time, and reduced the duration of myoclonic and tonic-clonic seizures following PTZ injection. The PTZ produced oxidative stress so that malondialdehyde and hydrogen peroxide levels were increased and catalase and peroxidase activity decreased. Pretreatment with DAEO and α-pinene significantly inhibited the above-mentioned enzymatic changes in PTZ-treated animals. Conclusion: The results suggest that α-pinene, at teast in part, was responsible for the induction of the anticonvulsant and antioxidant effects of DAEO in rats.

The contents of alcohol soluble extracts and water-soluble extracts in different growth patterns and years are: wild products<perennial cultivation<annual cultivation; the contents of volatile oil are: wild products>perennial cultivation>annual cultivation; the contents of four chromones are: wild products>perennial cultivation and annual cultivation. There was no significant difference between the sum of the two indexes in the Pharmacopoeia of perennial cultivation and wild products. 4 chromones showed no toxicity to RAW264. 7 cells at 5 mg·L-1. The release of NO and TNF-α was inhibited by 4 chromones and the anti-inflammatory effect of cimifugin was the best. In summary,there are obvious differences in appearance characteristics,internal quality and effects between different growth patterns and years. It showed that the wild products were superior to the perennial cultivation and the perennial cultivation was superior to the annual cultivation. In order to alleviate the shortage of wild S. divaricata resources,it is suggested that the Chinese Pharmacopoeia standard should increase the character of decoction pieces of perennial cultivation,and properly raise the limit requirement of the sum of the two indexes in the Chinese Pharmacopoeia to ensure the clinical demands and effect.

Collection and sorting of medicinal plants in Chinese Apiaceae( Umbelliferae) / 中国中药杂志

The family Apiaceae( Umbelliferae) includes some of the world's most important medicinal plants,with more than 100 species recorded in the traditional Chinese medicine,of which more than ten species are commonly used medicinal materials. However,due to morphological similarities,high market demands and regional factors,substitutes and adulterants are often mixed with genuine in the medicinal market. Therefore,a comprehensive sorting for these poorly known plants has been done in this study by combining market survey with literature review,including its species,distribution,price and substitutes. According to the statistics,there are 65 genera and 262 species of medicinal plants of Apiaceae in China,with medicinal part mostly from radix and rhizoma. Sichuan province is the most abundant in distribution and planting resources,with about 137 species,followed by Yunnan,Hubei and Gansu provinces.Furthermore,we summarized the genuine and substitutes of 11 medicinal plants,e. g. Bupleurum,Angelica and Peucedanum etc.,which found that the medicinal plants of Apiaceae were substituted or mixed in different taxonomic ranks. This study would contribute to reduce the risk of medicine misuse,as well as explore other plants of Apiaceae with potential medicinal value,to achieve sustainable development of related industries.

Network pharmacological study of Schizonepetae Herba and Saposhnikoviae Radix in treatment of ulcerative colitis / 中国中药杂志

The aim of this paper was to screen the active targets of Schizonepetae Herba and Saposhnikoviae Radix in the treatment of ulcerative colitis by means of network pharmacology,and to investigate their mechanism of action. The effective components of Schizonepetae Herba and Saposhnikoviae Radix were screened out by traditional Chinese medicine systematic pharmacological( TCMSP)database,with oral bioavilability( OB) ≥30% and drug-like( DL) ≥18% selected as the thresholds. Target PPI network was built between the main components and their corresponding targets. One hundred and eighty-two human genes corresponding to the medicine target sites were obtained from Uniprot database; 3 874 genes corresponding to ulcerative colitis were obtained from Genecard database.A total of 115 intersection genes were screened from disease genes and medicine genes,and the PPI interaction analysis was conducted by using String tool. Disease-target PPI network was drawn by using Cytoscape software,and component-target-disease network was constructed. One hundred and eight nodes and 1 882 connections were found,and then Cytoscape software was used to merge the networks and filter the core network for gene GO function analysis and KEGG pathway enrichment analysis. The mechanism of Schizonepetae Herba and Saposhnikoviae Radix was then verified by animal experiment. Gene GO functional analysis suggested that biological process,molecular functions and cell components were involved,and it was found that ulcerative colitis might be related to transcription factor activity,and cytokine receptor binding,etc. Gene KEGG pathway enrichment analysis showed that the mechanism of ulcerative colitis might be associated with TNF and Toll-like receptors( TLRs) signaling pathway-mediated cytoinflammatory factors interleukin-1( IL-1) and interleukin-6( IL6). The possible mechanism of the effective components of Schizonepetae Herba and Saposhnikoviae Radix in treating ulcerative colitis might be related to intervening the cytokine receptor binding of TNF and TLRs signaling pathways,reducing the transcription of nuclear factor-kappaB( NF-κB),and inhibiting the secretion of intestinal inflammatory factors IL-1 and IL-6.

Stereological assessment of nephroprotective effects of Trachyspermum ammi essential oil against carbon tetrachloride-induced nephrotoxicity in mice / Evaluación estereológica de los efectos nefroprotectores del aceite esencial de Trachyspermum ammi contra la nefrotoxicidad inducida por tetracloruro de carbono en ratones

Trachyspermum ammi (T. ammi) has been used in folk medicine as anti-inflammatory, antipyretic, antibacterial, antifungal agent. The present study was conducted to investigate the protective effect of Trachyspermum ammi (T. ammi) essential oil against CC14- induced nephrotoxicity in mice. Thirty-five mice were divided into five groups as follows; positive control received olive oil 1 mL/ kg/ip, negative control received CC14 1 mg/kg/ip + 0.5 mL distilled water orally and tree treatment groups which received CC14 similar to the negative control and 200, 800 and 1600 µg/kg of T. ammi essential oil, respectively. All treatments were done twice a week (Saturday and Wednesday) for 45 days. On the last day, blood was sampled for urea and creatinine assessment and the left kidney was removed for stereological estimations. Essential oil of T. ammi at high dose significantly (p ≤ 0.05) decreased serum levels of creatinine and urea in comparison with CC14-treated group. Total volume of the kidney, cortex, proximal convoluted tubules (PC), glomerulus, vessels and interstitial tissue as well as total length of PC and vessel were significantly (p ≤ 0.05) increased following CC14 administration and were restored toward normal levels at high dose of T. ammi. Also, high dose of T. ammi improved glomerular loss significantly (p ≤ 0.05) as compared with CC14-treated group. Due to the chemical composition of T. ammi essential oil such as tymol, p-cymene, γ-terpinene which are antioxidant, it can be concluded that the essential oil of T. ammi can ameliorated renal injury induced following CC14 toxicity via its antioxidant components.

En la medicina popular se ha utilizado el aceite esencial de Trachyspermum ammi (T. ammi) como agente antiinflamatorio, antipirético, antibacteriano y anti fúngico. El presente estudio se realizó para investigar el efecto protector de Trachyspermum ammi (T. ammi) aceite esencial contra la nefrotoxicidad inducida en ratones. Treinta y cinco ratones fueron divididos en cinco grupos de la siguiente manera; el control positivo recibió 1 mL / kg / ip de aceite de oliva, el control negativo recibió 1 mg / kg / ip + 0,5 mL de agua destilada por vía oral y grupos de tratamiento arbóreo que recibieron un control similar al negativo y 200, 800 y 1600 mg / kg de T. aceite esencial de T. ammi, respectivamente. Todos los tratamientos se realizaron dos veces por semana (sábado y miércoles) durante 45 días. En el último día de tratamiento, se tomaron muestras de sangre para evaluar la urea y la creatinina, y se extrajo el riñón izquierdo para realizar estimaciones estereológicas. El aceite esencial de T. ammi a dosis altas significativamente (p ≤ 0,05) disminuyó los niveles séricos de creatinina y urea en comparación con el grupo tratado. El volumen total del riñón, la corteza, los túbulos contorneados proximales (PC), el glomérulo, los vasos y el tejido intersticial, así como la longitud total de la PC y el vaso aumentaron significativamente (p ≤ 0,05) después de la administración y se restablecieron a niveles normales con dosis altas de T. ammi. Además, una dosis alta de T. ammi mejoró significativamente la pérdida glomerular (p ≤ 0,05) en comparación con el grupo tratado. Debido a la composición química del aceite esencial de T. ammi como timol, p-cimeno, 𝛾-terpineno con propiedades antioxidantes, se puede concluir que el aceite esencial de T. ammi puede mejorar la lesión renal inducida después de la toxicidad a través de sus componentes antioxidantes.
