目的:建立酸枣仁颗粒的质量标准。方法:采用HPLC-ELSD测定了知母中菝葜皂苷元的含量,采用TLC对酸枣仁、知母进行定性鉴别。结果:菝葜皂苷元在0.672～5.040μg峰面积常用对数值对进样量常用对数值呈良好的线性关系,r=0.99938,平均回收率97.5%,RSD 1.22%,TLC能对酸枣仁、知母进行专属定性分析。结论:所建立的方法可准确地进行定性、定量检测,重复性好,可作为酸枣仁颗粒的质量控制。
Objective: To establish the quality standard of Suanzaoren granules. Methods: HPLC-ELSD was used to determine the content of Smilagenin in Anemarrhena asphodeloides Bge., And qualitative identification was carried out by using TLC. Results: The logarithmic value of the saponins in the range of 0.672 ~ 5.040μg peak area showed a good linear relationship with the common logarithm of injection volume, r = 0.99938, the average recovery rate was 97.5%, RSD 1.22% Female specific qualitative analysis. Conclusion: The established method can accurately qualitative and quantitative detection, reproducibility, and can be used as the quality control of Suanzaoren granules.
