目的:采用HPLC法测定参芍盆炎净合剂中芍药苷的含量;方法:采用Waters SunfireTM C18色谱柱,以乙腈-0.1%磷酸溶液(15∶85)为流动相,检测波长为230 nm;结果:芍药苷在0.058~1.160μg之间线性关系良好,相关系数为0.999 9,平均回收率为98.8%,RSD为0.95%;结论:该方法稳定可靠,可用于参芍盆炎净合剂中芍药苷的含量测定。
Objective: To determine the content of paeoniflorin in Shenqianpenyanjing mixture by HPLC; Method: Waters SunfireTM C18 column with acetonitrile-0.1% phosphoric acid solution (15:85) as the mobile phase and detection wavelength at 230 nm; : Paeoniflorin had a good linear relationship between 0.058 and 1.160μg with a correlation coefficient of 0.999 9. The average recovery was 98.8% and the RSD was 0.95%. Conclusion: This method is stable and reliable, and it can be used as a paeoniflorin in Shenqipenyanjing mixture. The determination of the content.
