摘 要:目的:用HPLC—ELSD测定血塞通注射液中三七皂苷R1、人参皂苷Rg1、Re及Rb1的含量。方法:色谱柱填料为氨基键合硅胶,流动相为乙腈-水(80:20);漂移管温度为90℃,载气流速为2.1L·min^-1。结果:三七皂苷R1、人参皂苷Rg1、Re及Rb1的线性范围和相关系数分别为:0.30—2.01μg(r=0.9991)、1.50~9.98μg(r=0.9997)、0.45~3.00μg(r=0.9992)及1,20—8.03μg(r=0.9996);回收率(n=6)分别为103.1%(RSD=2.7%)、98.1%(RSD=2.3%)、102.8%(RSD=2.6%)及96.9%(RSD=2.5%)。结论:该方法简便、准确、分离效果好,无干扰,可用于血塞通注射液的质量控制。Objective:To establish the quantitative method of Notoginsenoside R1, Ginsenoside Rg1 ,Re and Rb1 in Radix Notoginseng by HPLC-ELSD. Method: The column used was a Lichrospher NH2(4. 6 mm ×250mm) packed with a 5 μm stationary phase. The mobile phase consisted of acetonitrile-water(80: 20). The temperature of drift tube was 90 ℃ and the nebulizer nitrogen flow rate was 2. 1 L ·min^- 1. Result: A good linearity was obtained with the correlation coefficients ranged from 0. 30 - 2. 01 μg (r = 0. 999 1 ), 1.50 - 9. 98 μg( r = 0. 999 7 ) ,0.45 - 3.00 μg( r = 0. 999 2) and 1.20 - 8.03 μg( r = 0. 999 6), respectively. The average recoveries of the four components ( n = 6 ) were 103.1% ( RSD = 2. 7% ), 98.1% ( RSD = 2. 3 % ), 102. 8% ( RSD = 2.6% ) and 96. 9% ( RSD = 2. 5% ), respectively. Conclusion: It was proved that the method with HPLC-ELSD was reliable, simple, well separated and precise, that could be used as principles of quantitative analysis.
