摘要
目的对加味生脉饮制剂的检验方法进行研究。方法采用薄层层析法对中药甘草、五味子进行鉴别。用HPLC法对甘草苷进行了含量测定。色谱柱:Nova-PakC18柱(4.6mm×150mm,4μm);流动相:乙腈-2.5%冰醋酸溶液(13:87);波长276nm;流速1.0mL/min-1。结果甘草苷的线性范围为0.0313μg～0.3130μg(r=0.9999),平均回收率为98.47%,RSD为1.10%。结论此法简便、分离效果好,准确,为制定制剂的质量标准提供了参考。
Objective To research the quality analysis method of ＂Jiawei shenmaiyin Oral Solution＂. Methods Radix et Rhizoma Glycyrrhizae and Fructus schisandrae chinensis were identified by TLC. The contents of Liquiritin in ＂Jiawei Shenmaiyin Oral Solution＂ was determined by HPLC. The chromatographic condition included Nova-Pak C18 column （4.6 mm×150mm,4μm） and the mobile phase consisting of acetonitrile -2.5% acetic acid （13：87）. Detector wavelength was at 276 nm. A flow rate was 1.0 ml/min^-1. Results Good relationship at the ranges of 0.0313 μg-0.3130 μg with correlation coefficient 0.9999. The average recovery of Liquiritin was 98.47%, and RSD was 1.10%. Conclusion It was proved that the method was reliable, simple, well-separated and precise, and thus could be used for quality control of ＂Jiawei Shenmaiyin Oral Solution ＂.
