摘要
目的:建立高效液相色谱法测定养阴清肺口服液中芍药苷的含量。方法:采用Alhima C18柱(4.6mm×250mm,5μm),以乙腈-水(13:87)为流动相,流速为1.0mL·min^-1,结果:以进样量为横坐标X,峰面积值为纵坐标Y,建立标准曲线方程:回归方程Y=1.27×10^5x-1.19×10^3,相关系数r=1.0000,结果表明芍药苷在0.20492~2.0492μg范围内呈良好的线性关系。结论:该方法准确,重复性好,可用于该药的质量控制。
Objective: To develop an HPLC method for determination of Paeoniflorin in Yangyin Qingfei Oral Liquid. Methods : An All- tima C18 column (4. 6 mm×250 mm, 5 μm) was adoped. The mobile phase was acetonitrile-water ( 13 : 87 ), at the flow rate of 1.0 mL · min^-1. Results:The linearity was obtained within the range of 0. 204 92 -2. 049 2μg(r = 1. 000 0) ;The average recovery (n = 6) was 100.67% ,and RSD was 0.72%. Conclusion:The method is convenient,accurate,reproducible, and can be used for quality control of the preparation.
