目的:建立调理通宝Ⅰ号胶囊的质量标准。方法:采用薄层色谱法鉴别黄芪、白术、佛手、木香,采用高效液相色谱法测定虎杖中有效成分大黄素的含量。结果:TLC鉴别斑点清晰,阴性对照无干扰。虎杖中有效成分大黄素在线性范围4.25~68.00μg·ml~(-1)内线性关系良好,r=0.999 9;平均加样回收率为95.22%,RSD为1.47%(n=6)。结论:通过方法学验证表明所建立的方法可用于调理通宝Ⅰ号胶囊的质量控制。
Objective: To establish the quality standard of Tongbao capsule No.1. Methods: Astragalus membranaceus, Atractylodes macrocephala, bergamot, Bergamot were identified by TLC, and the content of emodin in Polygonum cuspidatum was determined by high performance liquid chromatography. Results: TLC identification spots clear, negative control without interference. Polygonum cuspidatum active ingredient emodin in the linear range 4.25 ~ 68.00μg · ml ~ (-1) within a good linear relationship, r = 0.999 9; average recovery was 95.22%, RSD was 1.47% (n = 6). Conclusion: The method validation shows that the established method can be used to adjust the quality control of Tongbao Ⅰ capsules.
