银翘消疹合剂质量标准

Quality Standard of Yinqiao Xiaozhen Mixture

目的建立银翘消疹合剂的质量标准。方法采用薄层色谱法对银翘消疹合剂中金银花、连翘、牛蒡子进行薄层鉴别;采用高效液相色谱法测定银翘消疹合剂中黄芩苷的含量。结果薄层色谱中金银花、连翘、牛蒡子斑点清晰,专属性强;黄芩苷线性范围为0.122 5~1.531 2μg,r=0.999 9,平均加样回收率99.42%,RSD为2.19%。结论所采用的薄层色谱和高效液相色谱方法简便易行,专属性强,重复性好,可用于银翘消疹合剂的质量控制。

Objective To establish a quality standard of yinqiao xiaozhen mixture. Methods Preparation of Forsythia,Arctium lappa L.,and Honeysuckle were identified by TLC method. The concentration of baicalin in yinqiao xiaozhen mixture was determined by HPLC method. Results The qualitative identification method can detect Forsythia,Arctium lappa L.,and Honeysuckle.TLC spots were clear.TLC method has strong specificity. The linear range of baicalin was 0. 122 5-1. 531 2 μg,r =0.999 9,the average sample recovery rate was 99.42%,RSD was 2.19%,respectively. Conclusion The method is simple,accurate and repeatable,which can be used for quality control of yinqiao xiaozhen mixture.
