【Abstract】 Objective:To develop the quantitative method of notoginsenoside R1,ginsenoside Rg1,and Rb1 in Tongdi capsules by HPLC -ELSD. Methods:The column was packed with a DiamonsilC18(150mm × 4. 6mm,5μm) stationary phase. The mobile phase consisted of acetonitrile -water,eluted in gradient mode(0 ~ 5min,acetonitrile 20% ~ 25% ;5 ~ 20min,acetonitrile 25% ~ 45% ) with flow rate of 1. 0ml.min -1. Column tem-perature was set at 25℃. The temperature of driftube was 70℃. Results:The linear ranges of notoginsen... 更多还原 【关键词】 HPLC-ELSD; 三七皂苷R1; 人参皂苷Rg1; 人参皂苷Rb1; 通迪胶囊; 【Key words】 HPLC -ELSD; notoginsenoside R1; ginsenoside Rg1; ginsenoside Rb1; Tongdi capsules;
