摘要:

优化高速逆流色谱分离4 种茶黄素的方法。两相溶剂系统为正己烷- 乙酸乙酯- 甲醇- 水- 冰醋酸(1:5:1:5:0.25,V/V),固定相为体系的上相,下相为流动相,流速为2ml/min,仪器转速700r/min,进样量30mg。从茶黄素复合物中分离纯化得到茶黄素、茶黄素-3- 没食子酸酯、茶黄素-3'- 没食子酸酯和茶黄素-3, 3'- 双没食子酸酯,尤其使得两种酯溶性茶黄素(茶黄素-3- 没食子酸酯、茶黄素-3'- 没食子酸酯)达到较好的分离。

Abstract:

In this study, high-speed countercurrent chromatography (HSCCC) was used to separate theaflavins. The optimized wo-phase solvent system, flow rate, revolution speed and injection amount of HSCCC were hexane-ethyl acetate- methanolwater- cetic acid (1:5:1:5:0.25, V/V), 2 ml/min, 700 r/min and 30 mg, respectively. The upper phase was used as the stationary hase, while the lower phase was the mobile phase of HSCCC. Under these conditions, four theaflavins including theaflavin TF1), theaflavin 3-gallate (TF2A), theaflavin 3'-gallate (TF2B) and theaflavin 3, 3'-digallate (TF3) were separated out from rude extract. Especially, two kinds of ester theaflavins, TF2A and TF2B were better separated.

Key words: high-speed countercurrent chromatography (HSCCC), eparation, theaflavins
