摘要
目的:为进一步控制冠脉宁片的质量,建立HPLC法测定冠脉宁片中葛根素的含量。方法:采用回流提取法制备供试溶液,高效液相色谱法测定葛根素含量,色谱条件:Hypersil BDS C18柱,流动相为甲醇-水(25∶75),检测波长250nm,流速为1.0 mL/min,柱温20℃。结果:葛根素在0.348 0-1.392 0μg范围内线性关系良好(r=0.999 6),平均回收率为99.79%,RSD=0.42%(n=6)。结论:所建立方法简便可行,专属性强,重现性好,可用于冠脉宁片的质量控制。
Objective: To develop an assay of puerarin in Guan-mai-ning Tablet by HPLC so as to control the quality of Guan-mai-ning Tablet further.Method: HPLC was used in the quantitative analysis of puerarin in the sample.The separation was performed on Hypersil BDS C18 column at 20℃ with a mixture of methanol-aquaefer(25∶75) as mobile phase.The detection wavelength was set at 250nm and the flow rate was 1.0 mL·min–1.Result: The linear range of puerarin was 0.348 0-1.3920 μg(r=0.999 6),the average recovery was 99.79 %,RSD = 0.42% %(n = 6).Conclusion: The method is simple and feasible.Its specificity is accurate and the reproducibility is good.It is suitable for the quality control of Guan-mai-ning Tablet.
