Abstract:
AIM:To determine icatiin,psoralen and isopsoralen in Yishen Buxue Capsule(Herba Epimedii;Fructus Psoraleae;Sanguis Draconis;Cortex Eucommiae,etc)by PR-HPLC.METHODS:The determination of icariin was carried out by HPLC with a Agilent HC-18(150 mm?4.6 mm,5 ?m)column,acetonitrile-water(30∶70)was as a mobile phase,detection wavelength was at 270 nm;With the same Agilent HC-18 column for psoralen and isopsoralen,the mobile phase was methanol-water(52∶48),detection wavelength was at 246 nm.RESULTS:Icariin showed a good linear relationship at the range of 0.110 4-0.883 2 ?g(r2= 0.999 8),the avearge recovery of icariin was 97.49%(RSD=1.47%,n=6).Psoralen also showed a good linear relationship at the range of 0.041 04-0.451 44 ?g(r2= 0.999 0),the average recovery for it was 104.51%(RSD= 1.58%,n=6);Isopsoralen showed a good linear relationship at the range of 0.037 52 ?g-0.412 72 ?g(r2= 0.999 9),the average recovery of isopsoralen was 103.01%(RSD=1.01%,n=6).CONCLUSION:The methods are sensitive,accurate,reproducible,specific and can be used for quality control of Yishen Buxue Capsule.
