Abstract:Objective To establish a high performance liquid chromatography(HPLC)method for simultaneous determination of main components of Tetrahydropalmatine,Paeoniflorin,TanshinoneⅡA,Hesperidin,Emodin,Schisandrin A and Chrysophanol in Huangqi Hugan Capsules.Methods HPLC was used to detect the aforementioned components in Huangqi Hugan Capsules.The column was CNW Athena C18 and the mobile phase was methanol(A)and 0.1%aqueous solution of phosphoric acid(B)in gradient elution.The flow rate was 1.0 ml/min at 30℃column temperature.The detection wavelength were 210 nm for Tetrahydropalmatine,230 nm for Paeoniflorin,Hesperidin and Schisandrin A,and 265 nm for TanshinoneⅡA,Emodin,and Chrysophanol were 265 nm.The linear range,recovery,and repeatability of each component in Huangqi Hugan Capsules were examined.Results The linear ranges of Tetrahydropalmatine,Paeoniflorin,Hesperidin,Schisandrin A,Tanshinone ⅡA,Emodin and Chrysophanol were 1.26-25.20 μg/ml(r=0.9996),7.03-140.60 μg/ml(r=0.9998),3.63-72.60 μg/ml(r=0.9997),2.11-42.20 μg/ml(r=0.9994),1.98-39.60 μg/ml(r=0.9995),3.10-62.00 μg/ml(r=0.9996),and 2.28-45.60 μg/ml(r=0.9995).The average recovery of 7 components (n=6)was 99.6%,98.9%,98.7%,99.2%,98.2%,98.8%,and 98.2%,respectively.RSD was 1.7%,1.0%,1.2%,1.5%,1.2%,1.2%and 1.0%,respectively.Conclusion The method is accurate and reproducible in a high recovery,which can be used for quality control of Huangqi Hugan Capsules.
