目的建立糖尿康胶囊(黄芪、葛根、丹参、人参、黄连等)的质量标准。方法采用薄层色谱法对方中的黄连、葛根、丹参进行鉴别。用薄层扫描法对方中所含黄芪甲苷进行含量测定。结果薄层鉴别色谱特征斑点明显。黄芪甲苷在1.046~5.230μg之间呈良好的线性关系,r=0.9994,平均回收率为98.38%,RSD=1.83%(n=6)。结论本法准确、稳定性好,可作为本复方制剂的质量控制标准方法。
Objective To establish the quality standard of Diafukang Capsule (Scutellariae Radix, Radix Puerariae, Salvia miltiorrhiza, Radix Ginseng, Rhizoma Coptidis, etc.). Methods TLC was used to identify Coptis chinensis, Radix Puerariae and Radix Salviae Miltiorrhizae. Astragaloside contained in the other party was determined by thin layer scanning. The results showed that the characteristics of the thin layer identification chromatogram were obvious. Astragaloside IV showed a good linear relationship between 1.046 ~ 5.230μg, r = 0.9994, the average recovery was 98.38%, RSD = 1.83% (n = 6). Conclusion This method is accurate and stable, and it can be used as a standard method for quality control of this compound preparation.
