目的 :建立三消丹胶囊中黄芪甲苷的测定方法。方法 :在λS=5 30nm ,λR=70 0nm用薄层色谱扫描法测定黄芪甲苷的含量。结果 :黄芪甲苷在 1.0 7～ 5 .35 μg范围内线性关系良好 ,(r=0 .9995 ) ,平均回收率为 96 .1% ,RSD =1.9%。结论 :该法准确、可靠、灵敏度高、重现性好 ,可用于该制剂中黄芪甲苷的含量测定及质量控制。
Objective : To establish a method for determination of astragaloside IV in Sanxiaodan capsule. Methods: The content of astragaloside IV was determined by thin layer chromatography at λ S = 5 30 nm and λ R = 70 nm. Results: Astragaloside had good linearity in the range of 1.0 7-5.35 μg (r=0.9995). The average recovery was 96.1% and RSD was 1.9%. Conclusion: The method is accurate, reliable, sensitive and reproducible. It can be used for the determination and quality control of astragaloside IV in this preparation.
