摘要: 本研究建立了高速逆流色谱法分离纯化灯心草中四个主要菲类成分effusol、dehydroeffusol、juncusol、dehydrojuncusol的方法。以环己烷-乙酸乙酯-甲醇-水为溶剂体系,上相为固定相,下相为流动相,流速2mL/min,主机转速850 rpm,温度25 ℃,对灯心草经80%乙醇回流提取,乙酸乙酯超声萃取得到的粗提物经高速逆流色谱2次纯化,得到dehydroeffusol、effusol、dehydrojuncusol、juncusol的纯度分别为99.3%、98.5%、98、7%、97.4%。

Abstract: This study is to establish the high-speed counter-current chromatography method for purification of effusol,dehydroeffusol,juncusol,dehydrojuncusol from Juncus effusus L. A two-phase solvent system was composed of cyclohexane-ethyl acetate-methanol-water(5:3:5:3),The upper phase was stationary phase while the lower as mobile phase,the flow rate was 2 mL/min,the revolution speed was 850rpm,and the emperature was 25 ℃.The ethyl acetate extracts of Juncus effusus was purified by HSCCC twice.The purity of effusol,dehydroeffusol,juncusol,dehydrojuncusol was 99.3%,98.5%,98.5%,97.4%.

Key words: Juncus effusus, phenanthrenes, High-speed counter-current chromatography, separation
