阳春片的质量标准研究

Study on the Quanlity Standard of Yangchun Tablets

目的建立阳春片质量控制方法。方法用薄层色谱法对该药中的淫羊藿、山茱萸进行定性鉴别;采用高效液相色谱法测定淫羊藿苷含量。结果薄层色谱鉴别斑点清晰,阴性对照无干扰,淫羊藿苷在20～1000ng内线性关系良好(r=0.9999),平均回收率为99.12%,RSD为1.67%(n=6)。结论该方法操作简便,结果稳定可靠,专属性强,可为该制剂的质量控制提供参考。

OBJECTIVE To establish the method for quality control of Yangchun tablets.METHODS Epimedii,ursolic acid were indentified by TLC.The content of epimedii was determined by HPLC.RESULTS The spots of TLC were distinct,the negative sample had no interference.The linear regression for icariin was obtained over the range of 20～1 000 ng（r=0.999 9）.The average recovery was 99.12%,RSD=1.67%（n=6）.CONCLUSION The established method is simple,feasible and repeatable,and can be used for the quality control of Yangchun tablets.
