摘要:

本文建立了一种灵敏、高效的同时测定大鼠血浆中三种人参皂苷Rg1, Rb, Re1的高效液相色谱法。采用C18(150 mm×4.6 mm)色谱柱进行分离; 以乙腈水为流动相梯度洗脱。通过研究发现标准曲线相关系数高于0.998, 线性范围分别如下: 人参皂苷Rg11.0–30.0 μg/mL; 人参皂苷Re0.5–15.0 μg/mL; 人参皂苷Rb10.5–200.0 μg/mL。人参皂苷(Rg1ReRb1)三个质控浓度的样品在4 ºC放置24小时, –20 ºC保存30, 三次冻融循环后均稳定。样品的日内、日间精密度的RSD值均小于6.0%, 平均回收率在96.1%–118.6%之间。人皂苷Rg1ReRb1的最低定量限分别为1.0, 0.5, 0.5 μg/mL。实验证明, 本研究所建立的方法能够成功地应用于大鼠血浆中参麦注射液三种人皂苷成分(Rg1ReRb1)的药动学研究。

Abstract:

In the present study, we developed a sensitive and efficient high performance liquid chromatography (HPLC) method for the simultaneous determination of three ginsenosides (Rg1, Re, Rb1) in rat plasma. Chromatographic separation was performed on a C18 (150 mm×4.6 mm) column utilizing gradient elution profile and a mobile phase consisting of (A) water and (B) acetonitrile. The calibration curve, with a great correlation coefficient greater than 0.998, was linear over the range of 1.0–30.0 μg/mL for ginsenoside Rg1, 0.5–15.0 μg/mL for ginsenoside Re, and 0.5–200.0 μg/mL for ginsenoside Rb1. The intra- and inter-day precisions for three ginsenosides (Rg1, Re, Rb1) were all less than 6.0%, and average recovery, examined at three concentration levels, ranged from 96.1% to 118.6%. The samples was stable within 24 h at 4 ºC storage, and 30 d at –20 ºC storage with three freeze-thaw-assay cycles. The low limits of quantification (LOQ) were 1.0, 0.5 and 0.5 μg/mL for Rg1,Re and Rb1, respectively. Taken together, the newly developed method was successfully applied to study the pharmacokinetics of ginsenoside Rg1, Re and Rb1 in rat plasma after intravenous administration of SHENMAI injection (SMI).
