HPLC-MS/MS法测定十批参芦中人参皂苷Rg1、Re和Rb1的含量
Jiangsu Journal of Traditional Chinese Medicine（2017）
Abstract
目的:建立同时检测参芦中人参皂苷Rg1、Re和Rb1含量的HPLC-MS/MS方法,测定十批参芦中人参皂苷Rg1、Re和Rb1的含量.方法:采用液质联用法(HPLC-MS/MS),色谱柱为SHIMADZU VP-ODS(4.6mm×150mm),流动相为乙腈-0.1%甲酸水,流速0.5mL/min,柱温40℃.质谱条件:正离子检测模式,用于定量分析的离子对分别为:Rg1m/z823.3→643.6,Rem/z969.7→789.6和Rb1m/z1131.5→365.3.结果:人参皂苷Rg1、Re、Rb1线性关系良好.结论:该方法简便、准确、快速,可用于参芦中人参皂苷Rg1、Re和Rb1的含量检测.
