生脉颗粒质量标准研究

摘要

Objective:To establish a method for quality standard of ShengMai granules. Methods:The contents of schisandrin in WuWeiZi (Schisandra chinensis) were determined by HPLC and distinguished by TLC. Chromatographic column:phenomenex Luna C18 (150×4.60 mm, 5μm);mobile phase:methyl alcohol-0.1%phosphoric acid solution (60∶40);flow rate:1.0 mL/min;detection wavelength:250 nm. Results:TLC method was simple and the blank test demonstrated no interference. Schisandrin demonstrated better linear relationship in the range between 0.0 712 and 2.136μg, r=0.9 99 9, average recovery rate was 97.23%. Conclusion:The method is simple, rapid, specific and feasible.%目的：建立生脉颗粒质量标准控制方法。方法：采用TLC五味子薄层鉴别方法以及HPLC法测定五味子中五味子醇甲的含量。色谱柱：phenomenexLuna C18(150×4.60 mm，5μm)；流动相：甲醇-0.1%磷酸溶液(60∶40)；流速：1.0 mL/min；检测波长：250 nm。结果：薄层鉴别方法简单，阴性无干扰；五味子醇甲在0.0712～2.136μg呈良好的线性关系，r=0.9999，平均回收率为97.23%；结论：该方法简单、快速、专属性强、可操作性强。
