目的:对不同厂家黄芩配方颗粒进行质量比较和分析,为制订统一的质量控制方法提供依据。方法:对不同厂家15批黄芩配方颗粒进行外观性状考察、薄层色谱鉴别及黄芩苷高效液相色谱法含量测定。结果:不同厂家及同一厂家不同批号间有一定差异,但差异不大。个别厂家产品存在质量不稳定问题。结论:建议制定统一的黄芩配方颗粒的质量控制标准,保证产品质量稳定可控。
Objective: To compare and analyze the quality of Huangqi formula granules from different manufacturers, and to provide basis for formulating a unified quality control method. Methods: The appearance traits of 15 batches of Astragalus membranaceus granules from different manufacturers were investigated, thin layer chromatography was used to identify and the content of baicalin was determined by HPLC. Result: There are certain differences between different manufacturers and the same manufacturer with different batch numbers, but the difference is not significant. The quality of individual products is unstable. Conclusion: It is recommended to formulate uniform quality control standards for Huangqi formula granules to ensure stable and controllable product quality.
