Abstract:
AIM To establish an HPLC method for the simultaneous content determination of echinacoside,verbascoside,aucubin,pinoresinol diglucoside,epimedin A,epimedin B,epimedin C,icariin and baohuoside Ⅰ in Jingang Tablets (Cistanches Herba,Eucommiae Cortex,Epimedii Folium,etc.).METHODS The analysis of 50％ methanol extract of this drug was performed on a 30 ℃ thermostatic Agilent TC-C18 column (250 mm × 4.6 mm,5 μm),with the mobile phase comprising of (methanol-acetonitrile)-0.2％ phosphoric acid flowing at 1.0 mL/min in a gradient elution manner,and the detection wavelengths were set at 330,208 and 270 nm.RESULTS Nine constituents showed good linear relationships within their own ranges (r ＞ 0.999 0),whose average recoveries were 96.64％-100.08％ with the RSDs of 0.71％-1.76％.CONCLUSION This sensitive and accurate method can be used for the quality control of Jingang Tablets.
