摘要
目的 建立银杏芪血通胶囊中阿魏酸的含量测定方法.方法 采用HPLC 法,色谱条件为：色谱柱：EclipseXDB-C18;流动相：乙腈-0.085%磷酸溶液（17：83）;流速：0.8 ml·min-1;检测波长：316nm.结果 阿魏酸在0.0456～0.1824μg范围内线性关系良好（r=1.0000）,平均回收率为99.44%,RSD=1.09%（n=6）.结论 本方法 操作简便,专属性强,结果 准确,可用于银杏芪血通胶囊的质量控制.
Objective： To set up a method to determination of Ferulic acid in yinxingqixuetong capsules. Method：The content of ferulic acid determined by HPLC .The chromatographic system consisted of C 18 column,using aeetonitrile-0.085% phosphate solution（17： 83） as mobile phase.The content was detected at a waveleng of 316 nm,the flow rate was 0.8 ml·min^-1 .Results： The ferulic acid have a good tinear rolatim in the range of 0.0456-0.1824 μg （r=1.0000）,the average recovery was 99.44% and RSD=1.09%（n=6）. Conolusion： The established method is simple, sensitive and accuracy .It can be used for quality control of yinxingqixuetong capsules.
