目的:建立高效液相色谱法测定雷公藤多苷片中雷公藤内酯甲的含量。方法:样品以甲醇提取后直接测定,使用Phenomenex Gemini C18色谱柱(250 mm×4。6 mm,5μm),以0。02 mol·L-磷酸二氢钾溶液-乙腈(32∶68)为流动相,流速1。0ml·min-1,检测波长为210 nm,柱温:室温。结果:雷公藤内酯甲线性范围为18。0~90。0μg·ml-1(r=0。999 7),平均回收率为102。61%,RSD为0。83%(n=6)。结论:本方法简便、准确、重复性好,可用于雷公藤多苷片的质量控制。
Determination of Wilforlide A in Tripterygium Tablets by HPLC
Objective: To establish a method for determination of wilforlide A in tripterygium tablets by HPLC. Method: Samples were extracted with methanol,the HPLC analysis was performed nn a Phenomenex Gemini C18(250 mm ×4.6 mm,5 μm) column,the mobile phase was 0. 02 mol·L-1 monobasic potassium phosphate - acetonitrile (32-68) wilh a flow rate of 1. 0 ml·min-1,the detection wavelength was 210nm and the analysis was operated at room temperature. Result: The linear range of wilforlide A was 18. 0- 90. 0 μg ·ml-1(r-0. 9997), and the average recovery was 102.61% with RSD of 0. 83% (n= 6). Conclusion: The method is convenient, accurate and suitable for the quality control of tripterygium tahlets.
