ABSTRACT Objective:To develop an HPLC method for determination the content of paeoniflorin in Bazhen Yimu tables.Method: Hypersil ODS2 C18column(250 mm×4.6 mm,5 μm)was used,the mobile phase was a mixture of acetonitrile0.1 mol•L-1 phosphoric acid solution(15∶85),the flow rate was 1.0 ml•min-1,the column temperature was room temperature,the detection wavelength was at 230 nm.Result: The linear range of paeoniflorin was 0.15-1.2μg(r=0.999 9).The average recovery was 99.9% with RSD0.8%(n=5). Conclusion:The method is selective and reproducible,it can be used for determination the content of paeoniflorin in Bazhen Yimu tablets.
