双瓜降糖胶囊质量标准研究

Study on Quality Standards for Shuanggua Jiangtang Capsules

目的 :建立双瓜降糖胶囊的质量标准。方法 :采用 TL C法对处方中苦瓜干、猪胰、黄芪进行鉴别 ;用薄层扫描法测定黄芪甲苷的含量。结果 :在 TL C色谱中检出苦瓜干、猪胰、黄芪 ;黄芪甲苷在 1.0 0 146～ 5 .0 0 63 0μg之间呈良好线性关系 ,r=0 .9999,平均回收率 98.0 2 % ,RSD为 2 .78%。结论

Objective:To establish the quality standards for Shuanggua Jiangtang Capsules.Methods:Momordica charantia L.; Sus scrofa domestica Brisson; Radix Astragali were identified by TLC and astragoloside Ⅳ was determined by TLC-scanning.Results:Momordica charantia L.; Sus scrofa domestica Brisson;Radix Astragali could be detected by TLC.Astragaloside Ⅳ showed a good linear relationship at a range of 1.001 46～5.006 30 μg,r=0.999 9.The average recovery was 98.02%,and RSD was 2.78%.Conclusion:The method can be used to control the quality of Shuanggua Jiangtang Capsules.
