ABSTRACT
The commodity specification and grade is a symbol of quality of Chinese medicinal materials,a standard to measure and evaluate the quality of Chinese medicinal materials,and an important part of the quality control system of Chinese medicinal materials.This article reviewed relevant research literature of commodity specification and grade of Chinese medicinal materials,including the formation and policy support of specification and grade.It analyzed the specific research examples of the commodity specification and grade of Chinese medicinal materials according to the classification of medicinal parts,and summarized the research conditions of the commodity classification at present stage.Aiming at the current research difficulties and the lack of unified standards in specification and grade of Chinese medicinal materials,some advice including research objects,methods,management,publicity,promotion and application are put forward,so as to provide references for the research on the commodity specification and grade of Chinese medicinal materials.
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.
