Abstract
AIM To establish an HPLC-ELSD method for the simultaneous content determination of euscaphic acid,tormentic acid,crategolic acid,corosolic acid,ophiopogonin D,ophiopogonin D',methylophiopogonanone A and methylophiopogonanone B in Shenmai Zhisou Syrup (Eriobotryae Folium,Ophiopogonis Radix,Glehniae Radix,etc.).METHODS The analysis of methanol extract of this drug was performed on a 35 ℃ Alltima C18 column (4.6 mm × 250 mm,5 μm),with the mobile phase comprising of (acetonitrile-methanol)-0.5％ ammonium acetate flowing at 0.7 mL/min in a gradient elution manner.RESULTS Eight constituents showed good linear relationships within their own ranges (r ＞ 0.999 0),whose average recoveries were 96.85％-99.43％ with the RSDs of 0.57％-1.33％.CONCLUSION This simple and accurate method can be used for the rapid quality control of Shenmai Zhisou Syrup.关键词
