目的:拟定苦参乳的质量标准以便进行质量控制。方法:对本品生物碱进行化学鉴别和薄层色谱鉴别。含量测定方法采用剩余中和法来测定其中生物碱的含量并对该方法测定样品的重复性以及加样回收率研究。结果:鉴别方法简便,重现性和专属性良好,含量测定方法重现性试验RSD(%)1.43%,回收率试验RSD(%)0.54%,每支含苦参总碱以氧化苦参碱(C_(15)H_(24)N_2O_2)计,应为标示量的80.0%~120.0%。结论:苦参乳鉴别和含量测定方法简便,重现性和专属性良好,有效控制了苦参乳质量。
Objective: To develop quality standards for matrine for quality control. Methods: The chemical alkaloids identified by TLC and TLC. Determination of the content of residual neutralization method to determine the content of alkaloids and the method for determining the sample repeatability and sample recovery study. Results: The identification method was simple, reproducible and specific. The RSD (%) was 1.43% and the RSD (%) was 0.54% in the reproducibility test of content determination method. (C_ (15) H_ (24) N_2O_2) should be 80.0% ~ 120.0% of the marked amount. Conclusion: The method for the identification and determination of matrine milk is simple, reproducible and specific, which effectively controls the quality of matrine milk.
