目的:建立通经蠲痹胶囊的质量控制方法。方法:采用薄层色谱法鉴别当归、马钱子;采用高效液相色谱法测定通经蠲痹胶囊中盐酸麻黄碱的含量。结果:薄层色谱中能明显地检出当归、马钱子;盐酸麻黄碱进样量在0.11～0.54μg范围内线性关系良好(r=0.9996)。盐酸麻黄碱的平均回收率为100.5%,RSD为1.2%(n=6)。结论:方法简便,准确,重现性好。可用于控制通经蠲痹胶囊的质量。
Objective: To establish the quality control method of Tongjing Huibai capsule. Methods: The Angelica sinensis and Strychnos nux-vomica were identified by TLC. The content of ephedrine hydrochloride in Tongjing Yingbi capsule was determined by high performance liquid chromatography. Results: The angelica and strychnos could be detected clearly in the thin layer chromatography. The linear range was 0.11 ~ 0.54μg (r = 0.9996) for the injection volume of ephedrine hydrochloride. The average recovery of ephedrine hydrochloride was 100.5% with RSD of 1.2% (n = 6). Conclusion: The method is simple, accurate and reproducible. Can be used to control the quality of Tongjing Yingbi capsule.
