ABSTRACT
OBJECTIVE： To predict the anti-inflammatory active components and mechanism of couplet medicine of Notopterygium incisum-Angelica pubescens. METHODS： According to the principle of oral bioavailability≥30％ and drug- likeness≥0.18， active components of N. incisum and A. pubescens were screened； TCMSP was used to predict and screen the potential target of them. Using “Anti-inflammatory” as keyword， inflammatory related target genes were retrieved from human gene database Genecards. Common target was screened by mapping the target genes of active ingredients from couplet medicine of N. incisum-A. pubescens. The active ingredient-target network was established by using Cytoscape 3.5.1 software. The screened targets were used to construct the target protein interaction （PPI） network on the STRING V 10.5 platform. Its anti-inflammatory mechanism was studied by KEGG signaling pathway and GO biological enrichment analysis. RESULTS： Totally 15 active components such as coumarin， beta-sitosterol， ammidin， nodakenin were selected from couplet medicine of N. incisum-A. pubescens. Acting on 49 targets such as transcription factor AP-1， PI3-kinase subunit gamma， estrogen receptor， they mainly involved 19 signaling pathways such as hepatitis B and cell apoptosis， and were involved in 47 biological processes such as regulating inflammatory response and prostaglandin biosynthesis. CONCLUSIONS： The anti-inflammatory mechanism of active components of couplet medicine of N. incisum-A. pubescens on multi-target， multi-channel and multi-biological processes is predicted， and it points out the direction for further anti-inflammatory mechanism study.
ABSTRACT
OBJECTIVE:To compare the contents of osthole and columbianadin in Argelica. pubescens in Wushan county, Wuxi county in Chongqing and other domestic areas in china. METHODS:HPLC was performed on the column of Shiseido Cap-cell Pak C18 with mobile phase of acetonitrile-water(gradient elution) at flow rate of 1.0 ml/min,detection wavelength was 330 nm,column temperature was 30 ℃ and volume injection was 10 μl. RESULTS:The linear range was 0.015 1-0.301 6 mg/ml(r=0.999 9) for osthole and 0.016 7-0.334 4 mg/ml(r=0.999 9) for columbianadin;RSDs of precision,stability and reproducibility tests were lower than 2.0%;recoveries were 98.46%-106.11%(RSD=2.34%,n=9)and 98.24%-102.69%(RSD=1.29%,n=9), respectively. CONCLUSIONS:The method is simple and good reproducibility,and and can be used for the contents determination of osthole and columbianadin in A. pubescens. The contents of osthole and columbianadin in A. pubescens of Wushan county in Chongqing are obviously higher than Wuxi county and other domestic areas in China.
