ABSTRACT

To provide the ancient literary evidence support for the clinical application and development of classical prescription based on systematical collection and analysis of the ancient Chinese medical literature containing Jinshui Liujun Jian, including its origin and development. Bibliometric analysis was used and information of Jinshui Liujun Jian in ancient Chinese medical literature was then collected for statistical analysis of formula compositions, main indications, dosage, preparation methods, etc. A total of 151 valid items of data were obtained from 48 ancient Chinese medicine books. Jinshui Liujun Jian was first recorded in Jingyue Quanshu written by ZHANG Jiebin. This prescription consisted of Rehmanniae Radix Praeparata, Angelicae Sinensis Radix, Pinelliae Rhizome, Citri Reticulatae Pericarpium, Poria and Glycyrrhizae Radix et Rhizome Praeparata cum Melle, and it was mainly used to treat the deficiency of lung and kidney, edema and excess production of phlegm, or Yin deficiency in the old, insufficient blood-qi, wind-cold evil, cough and disgusting, asthma and excessive phlegm. Doctors in later dynasties mostly followed the prescription compositions, dosages and indications in Jingyue Quanshu, and extended the clinical application of this prescription.

ABSTRACT

In this study,mouse models of benign prostatic hyperplasia induced by subcutaneous injection of testosterone propionate was used to investigate the therapeutic effect and mechanism of Urtica hyperborean( UW) extracts on prostate hyperplasia in mice. The effects of UW extracts on prostate index,serum epidermal growth factor( EGF) and dihydrotestosterone( DHT) in model mice were observed,and the EGF and anti-apoptotic factor( Bcl-2) mRNA expression levels were detected as well as pathological changes in prostate tissue. The results showed that the ethyl acetate extraction and alcohol soluble fraction of the UW could significantly reduce the prostate index,reduce the serum DHT and EGF levels( P<0. 01),and significantly decrease the EGF and Bcl-2 mRNA expression( P<0. 01),significantly improved the morphological structure of prostate tissue. The above results confirmed that ethyl acetate extract and alcohol-soluble parts of UW have a good preventive effect on mice prostatic hyperplasia model,and its mechanism may be to reduce androgen levels by regulating polypeptide growth factors and/or inhibiting cell hyperproliferation and promoting apoptosis. This study laid the foundation for the further research on UW.

ABSTRACT

This paper deals with the application of ultra-performance liquid chromatography tandem quadrupole time of flight mass spectrometry(UPLC-ESI-Q-TOF-MS/MS) method to rapidly determine and analyze the chemical constituents of methanol extract of Urtica hyperborea. We employed UPLC YMC-Triart C18(2. 1 mm×100 mm,1. 9 μm) column to UPLC analysis with acetonitrile-water(containing 0. 4% formic acid) in gradient as mobile phase. The flow rate was 0. 3 m L·min-1 gradient elution and column temperature was 30℃; the injection volume was 4 μL. ESI ion source was used to ensure the data collected in anegative ion mode. The chemical components of U. hyperborea were identified through retention time,exact relative molecular mass,cleavage fragments of MS/MS and reported data.The results indicated that a total of 31 compounds were identified,including 8 flavonoids,14 phenolic compounds,8 phenylpropanoids(4 coumarins and 4 lignans),and 1 steroidal compound,13 of which were confirmed by comparison. The UPLC-ESI-Q-TOF-MS/MS method could rapid identify the chemical components of U. hyperborea. The above compounds were discovered in U. hyperborea for the first time,which could provide theoretical foundation for further research on the basis of the pharmacodynamics of U. hyperborea.

ABSTRACT

The study is aimed to clarify the actual original plant, find out the usage status and the resource distribution of the Tibetan medicinal plant "Bangga". By using the way of the literatures survey, interview and investigation, it found out that the actual original plant of the Tibetan medicinal plant "Bangga" were the whole dried plant or the aerial part of Aconitum tanguticum or A. naviculare of Ranunculaceae, among which A. tanguticummainly distributed in Sichuan, Gansu, Qinghai, Tibet (Qamdo), and A. naviculare mainly distributed in Tibet. Sichuan, Gansu, Qinghai and other Tibetan areas mainly used the resources of A. tanguticum, Tibet (except the Qamdo area) mainly uses the A. naviculare, which resource was imminent in danger. Other species described in the literature were not used. It showed that the use of herbs related to their resources, it is recommended to strengthen the protection and guide the market.

ABSTRACT

<p><b>OBJECTIVE</b>To establish a method of TLC identification for Dida commonly used in Tibetan medicine from different species.</p><p><b>METHOD</b>With silica gel G as the stationary phase, and chloroform-methanol (40: 1) as mobile phase, oleanolic acid from different species of Dida was separated and identified.</p><p><b>RESULT</b>Oleanolic acid was detected in 70 kinds of Dida derived from the Gentianaceae Swertia, Halenia, Gentianopsis, Lomatogonium, and Saxifragaceae saxifrage, except for the saxifrage, there are some differences among different genera or subjection.</p><p><b>CONCLUSION</b>This TLC method can be used for identification of oleanolic acid in Dida from different species except saxifrage.</p>

ABSTRACT

<p><b>OBJECTIVE</b>To establish a method for determination of 10 ingredients such as gentiopicroside, sweroside, and mangiferin in India swertia, and settle the index components and their limits.</p><p><b>METHOD</b>By Welch materials AQ-C18 column, determination was conducted by the gradient elution with methanol and 0.4% formic acid as mobile phase, with column temperature 30 degrees C, flow rate at 1.0 mL x min(-1), and 254 nm as the detection wavelength.</p><p><b>RESULT</b>The linear relatives of 10 ingredients were good. The method showed the high precision and good reproducibility, and recovery rates were between 97% and 103%. The ingredients of market com-modities varied greatly.</p><p><b>CONCLUSION</b>This method is simple, sensitive, reproducible, and applicable to the determination of the main ingredients in India Swertia. Sweroside and mango glycosides were suggested as the index components for determination in Jia Di (Swertia chirayita), and their content limits are not less than 0.1%, 0.3%, respectively.</p>

ABSTRACT

<p><b>OBJECTIVE</b>To evaluate the medicinal reasonableness and resource utilization of Dida from different species.</p><p><b>METHOD</b>With common characteristic absorption peaks of HPLC fingerprints and SPSS cluster, the composition similarity of Dida from different species was evaluated.</p><p><b>RESULT</b>The composition similarity of HPLC fingerprints of 33 Dida samples from 15 species and 1 variety originated from Swertia, Halenia, Gentianopsis, Lomatogonium was difference. The original species can be clustered into four groups by the relative area of 10 common characteristic peaks of HPLC fingerprints. The compositions of four different genera are quite different.</p><p><b>CONCLUSION</b>Because of containing iridoids, xanthones, and triterpenes which have liver protection and cholagogue functions, all of species from Swertia, Halenia, Gentianopsis and Lomatogonium in Gentianaceae are classified as Dida in Tibetan medicine. According to the composition difference among different species, the HPLC fingerprints established for Dida from different source are an effective means to identify nd control the quality of Dida.</p>
