摘要
生脉散由人参、麦冬、五味子三味中药组成。其口服液为单糖浆液。有关人参制剂中人参皂甙的含量测定方法有重量法、比色法、薄层层析-比色法、薄层扫描法等。本文采用柱层析法提取人参总皂甙,然后利用二次展开成功地将总皂甙与糖完全分离并用薄层扫描法测定其含量,方法简单可靠。
An improved method for determination of ginseng saponins in oral liquid of Shenmai San is described. Ginseng saponins were extracted with n-butyl alcohol (saturated with water) on silica gel column. The scperation of sugar and saponins in the extract were carried out by twice-development, using water and nonaq. alcohol-water-cyclohexane (10: 8: 0.2) as mobile phase respectively. The average recovery of Re was found to be 100.6%, the coefficent of variation was 1.5%.
