摘要
目的:建立补肾温肺合剂中黄芪甲苷的含量测定方法。方法:利用HPLC—ELSD法,采用AgilentZORBAXC18色谱柱(150mm×4.6mm,5μm);流动相:甲醇-水(75:25);漂移管温度:80℃;气体流速:2.5ml·min-1。结果:黄芪甲苷对照品在0.297—4.944μg范围内呈良好线性关系(r=0.9997),平均回收率为98.13%,RSD为1.27%(n=9)。结论:本方法结果准确,重复性好,可作为该制剂的含量测定方法。
Objective: To establish the content determination method for astragaloside in Bushen Wenfei mixtures by HPLC-ELSD. Methods: HPLC with an Agilent ZORBAX C18 ( 150 mm×4.6mm,5μm) column was used. Methanol-water(75: 25)was used as the mobile phase and the flow rate was 0.8 ml·min-1. The drift tube temperature was 80℃ and the gas flow rate was 2.5 ml ·min-1. Results: The linear range of astragaloside was 0.297-4. 944 I-Lg ( r = 0.999 7 ). The average recovery was 98.13% with RSD of 1.27% ( n = 9). Conclusion: The method is with sufficient accuracy, stability and repeatability, and can be used in determination of Bushen Wenfei mixtures.
