摘要: 利用高速逆流色谱对大黄中的5个蒽醌活性成分进行了分离,当两相溶剂系统的组成是石油醚:乙酸乙酯:甲醇:水=8:2:8:1时,分离出大黄素;当两相溶剂比为3:4:3:2时,分离出大黄酸和芦荟大黄素;当溶剂比为12:2:12:1时,分离出大黄酚和大黄素甲醚;经高压液相色谱检测大黄素、大黄酸和芦荟大黄素、大黄酚和大黄素甲醚的含量分别为98.81%、99.15%、98.51%、98.89%和98.16%。

Abstract: Five anthraquinones from Rhubarb were separated by high speed countercurrent chromatography. When two-phase solvent system composition was petroleum ether:ethyl acetate:methanol:water (8:2:8:1), emodin was obtained. Rhein and aloe emodin were separated when the proportion of solvents was 3:4:3:2, while chrysophanol and rheochrysidin were separated at the proportion of solvents 12:2:12:1. The purities of emodin, rhein, aloe emodin, chrysophanol and rheochrysidin are 98.81%, 99.15%, 98.51%, 98.89% and 98.16% respectively by HPLC.

Key words: high speed countercurrent chromatography, aloe emodin, rhein, emodin, chrysophanol, rheochrysidin, separation
