摘要
目的:建立HPLC法测定珍菊降压片中蒙花苷含量。方法:采用ZORBAX Eclipse XDB-C18色谱柱,以乙腈-水(28∶72)为流动相,检测波长334nm。结果:蒙花苷在0.025~0.50μg线性关系良好,r=0.9994,平均回收率为98.7%(n=5),RSD为2.1%。结论:本法简便、准确、重复性好,可用于珍菊降压片中蒙花苷含量测定。
Objective: To establish HPLC for determining the content of linarin in Zhengjujiangya Tablet. Method: A HPLC method was developed. The chromatographic conditions are as follow ZORBAX Eclipse XDB - C18 column and acetonitrile - water (25: 75) as mobile phase, detection wavelength at 334nm. Result : The linear range of linarin was 0.025 - 0.05μg. The average recovery rate was 98.7% and RSD 2.7%. Conclusion: The method is simple and accurate with good repeatability, and can be used for determinate linarin in Zhengjujiangya Tablet.
