目的:建立扶正胶囊中人参皂苷Rg1、Re、Rb1超高效液相色谱(UPLC)测定方法。方法:采用Acquity1UPLCBEHC18色谱柱(2.1mm×100mm,1.7μm),以乙腈-水为流动相进行梯度洗脱,流速0.5mL/min,检测波长203nm,柱温40℃。结果:扶正胶囊中人参皂苷Rg1、Re、Rb1在14min内完全分离;人参皂苷Rg1和人参皂苷Re分离度达2.0,人参皂苷Rg1、Re、Rb1峰理论板数均超过20000;经外标法计算,含人参皂苷Rg1、Re、Rb1质量分别为0.71mg/g,3.841mg/g,10.61mg/g。结论:本法简便、准确、快速,可用于扶正胶囊中人参皂苷Rg1、Re、Rb1含质量测定。
Objective: To establish a method for the determination of ginsenoside Rg1, Re, Rb1 in Fuzheng Capsules by ultra performance liquid chromatography (UPLC). Methods: The mobile phase was eluted with acetonitrile using acetonitrile as the mobile phase. The flow rate was 0.5 mL / min. The detection wavelength was set at 203 nm and the column temperature was 40 ℃. Results: Ginsenosides Rg1, Re and Rb1 in Fuzheng Capsules were completely separated within 14min. The resolution of ginsenoside Rg1 and ginsenoside Re reached 2.0. The theoretical plates of Rg1, Re and Rb1 of ginsenosides all exceeded 20000; , Ginsenosides Rg1, Re, Rb1 quality were 0.71mg / g, 3.841mg / g, 10.61mg / g. Conclusion: The method is simple, accurate and rapid and can be used for determination of ginsenoside Rg1, Re, Rb1 in Fuzheng Capsules.
