高效液相色谱法快速测定参芪降糖胶囊中人参皂苷的含量

Fast Determination of Ginsenosides in Shengqi Jiangtang Capsule by High Performance Liquid Chromatography

  • 摘要: 建立了高效液相色谱法快速测定参芪降糖胶囊中人参皂苷Rg1、人参皂苷Re、人参皂苷Rd含量的方法. 采用3.5 μm Coreshell C18核壳型分离填料(3.0 mm×150 mm)为色谱柱,分别以纯乙腈、纯水为流动相进行梯度淋洗,流量为0.43 mL/min,柱箱温度为25 ℃,检测波长为203 nm. 人参皂苷Rg1、人参皂苷Re、人参皂苷Rd分别在5~400、20~800、5~400 μg/mL质量浓度范围内线性关系良好(R2大于0.999 6),加标回收率为95.89%~100.67%,相对标准偏差为1.04%~3.39%. 方法可以快速检测参芪降糖胶囊中人参皂苷的含量,准确度高,数据可靠,对仪器要求不高,易于接受,可用于人参皂苷的相关质量控制.

     

    Abstract: In order to determine the Ginsenoside Rg1, Ginsenoside Re and Ginsenoside Rd in Shengqi Jiangtang Capsule rapidly, a high performance liquid chromatographic (HPLC) method has been set up. Under optimized conditions, the analytes were carried out with acetonitrile, water as the mobile phase in a gradient elution manner at a flow rate of 0.43 mL/min and a wavelength of 203 nm on a 3.5 μm Coreshell column(3.0 mm×150 mm). The results showed that good linear relationships of Ginsenoside Rg1, Ginsenoside Re and Ginsenoside Rd within the mass concentrations of 5~400, 20~800, 5~400 μg/mL, respectively, and all the correlation coefficients were better than 0.999 6. The recoveries were 95.89%~100.67% and the relative standard deviations were 1.04%~3.39%. This rapid, accurate and reliable method can be used for the quality control of Shengqi Jiangtang Capsule without a high demand instrument.
