Abstract:
AIM:To establish the method for quality control of Jueming Jiangzhi Tablet(Semen Cassiae,Radix Polygoni multiflori,Herba Taxilli,Herba Artemisiae scopariae,etc.).METHODS:Radix Polygoni multiflori、 Herba Taxilli、 Herba Artemisiae scopariae、Semen Cassiae were identified by TLC.HPLC method for determining emodin and 2,3,5,4'-tetrahydroxydiphenylethylenic-2-O-?-D-glucoside in Jueming Jiangzhi Tablet were established.A Dikma Diamonsil C_ 18 column was used,the mobile phases were methanol-0.1% phosphate solution(85∶15)and acetonitrile-water solution(5∶15),respectively.The flow rate was 1.0 mL/min.The detection wavelength was at 254 nm and 320 nm,respectively.RESULTS:The spots on the TLC plate were clear.The negative control sample didn't disturb.A good linearity was obtained for emodin in the range of 0.131 2-1.312 0 ?g,r= 0.999 8.The average recovery was 99.80%,RSD=1.17%(n=6).A good linearity was obtained for 2,3,5,4'-tetrahydroxydiphenylethylenic-2-O-?-D-glucoside in the range of 0.580 0-5.800 0 ?g,r=0.999 8.The average recovery was 98.68%,RSD=1.36%(n=6).CONCLUSION:The methods are specific,accurate and reproducible,and can be used for the quality control of the product.
