脑脉一号胶囊中黄芪甲苷的定量研究

Quantitative Determination of Astragloside IV of Naomai No.1 Capsule

目的 :采用薄层扫描法测定脑脉一号胶囊中黄芪甲苷的含量。方法 :采用 CS-93 0 1薄层扫描仪 ,扫描方式采用锯齿扫描 ,零点设置为锯齿扫描斑点两边 (B.C.)为零。结果 :避免了背景对测定的干扰 ,方法简便 ,结果准确。结论 :在常规方法的基础上 ,采用适当的仪器方法 ,是测定色谱背景干扰较大的复方中黄芪甲苷含量的一种简单可行的方法。

Objective:The quantitative determinati on of astragloside IV of Naomai No.1 capsule was established by TLC-scanning meth od.Methods:The scanning mode was zigzag, zero set mode was B.C. by CS-9301 TLC-scanner.Results:The result showed t hat it could advoid the interference of TLC background. The method is simple, fa st, and accurate.Conclusion:On the basis of the normal met hod, a method to select a good scanning mode was obtained for quantitative deter mination of astragloside IV in complex prescription which TLC background was not clear enough.
