目的:建立羊芪通络胶囊的质量标准。方法:采用薄层色谱法对羊芪通络胶囊中的淫羊藿、麻黄、延胡索和穿山龙进行定性鉴别。采用HPLC-ELSD法测定黄芪甲苷的含量。结果:薄层色谱斑点清晰,阴性对照无干扰。黄芪甲苷的线性范围为0.2~4μg(r=0.9997),平均回收率为97.67%,RSD为2.39%(n=6)。结论:该方法专属性强、操作简便。
Objective: To establish the quality standard of Yang Qi Tongluo Capsule. Methods: Epimedium, Ephedra, Corydalis yanhusuo and Chuanhushan were identified by TLC. The content of Astragaloside Ⅳ was determined by HPLC-ELSD. Results: Thin-layer chromatography spots clear, negative control without interference. The linear range of astragaloside was 0.2-4μg (r = 0.9997). The average recovery was 97.67% with RSD of 2.39% (n = 6). Conclusion: This method is highly specific and easy to operate.
