摘  要:目的:用HPLC法测定龙胆泻肝丸中的黄芩苷的含量。方法:采用Nova-Pak C18柱(3.9mm×150mm,4μm),以甲醇-水-冰醋酸(45:55:1)为流动相,流速1.0ml/min,检测波长275nm。结果:对照品在0.815~4.075μg/ml范围内呈线性关系(r=0.9996),加样回收率平均为99.4%,RSD为1.12%。结论:本方法简便、准确、重复性好,可用于测定龙胆泻肝丸中黄芩苷的含量。OBJECTIVE To establish an HPLC method for determining baicalin in Longdan Xiegan Pills. METHODS The condition of HPLC was Nova- Pak C18 column( 3.9 mm× 150 mm,4 μm) ;mobile phase was methanol- water- acetic acid glacial( 45 : 55: 1 ) ,with a flow rate of 1.0 ml/min, UV detector at 275 nm. RESULTS The calibration curve showed linear (r = 0. 999 6 ) within the range of 0.815 -4. 075 μg/ml for baicalin, the average recovery was 99.4% ( n =6) ,RSD was 1.12%. CONCLUSION The method is simple, accurate and repeatability ,and suitable for the quality control of the drug.
