目的:探究定心胶囊质量工艺测定的研究方法。方法:以高效液相色谱法检测人参皂苷Rg1在中药益气养阴复方定心胶囊中的含量并通过薄层色谱鉴别法对处方中的丹参,黄芪和酸枣仁三位药材进行检测鉴别。结果:在薄层色谱中可检出丹参,黄芪和酸枣仁的特征斑点。人参皂苷Rg1在2.156~10.078μg范围内线性关系良好,r=0.999 7,精密度RSD=1.90%(n=5),重复性试验RSD=1.29%(n=5),其平均加样回收率为97.37%(RSD=1.90%,n=5)。结论:该方法准确性高,便于重复,易于操作,适合用于定心胶囊的质量检测。
Objective: To explore the method of determination of Dingxin capsule quality technology. Methods: The contents of ginsenoside Rg1 in Ding Yi Capsule of traditional Chinese medicine Yiqi Yangyin were detected by HPLC. The three herbs of Radix Salviae Miltiorrhizae, Radix Astragali and Zaosan were identified by TLC. Results: The characteristic spots of Radix Salviae Miltiorrhizae, Radix Astragali and Zizyphus Jujuba can be detected in TLC. Ginsenoside Rg1 had a good linear relationship in the range of 2.156 ~ 10.078μg with r = 0.999 7, RSD = 1.90% (n = 5), RSD = 1.29% (n = 5) 97.37% (RSD = 1.90%, n = 5). Conclusion: The method is accurate, easy to repeat, easy to operate and suitable for the quality testing of Dingxin capsule.
