摘要:

本实验考察了表面性质不同的3种吸附树脂对儿茶素EGCG和咖啡因的吸附性能,结果显示:3种树脂对咖啡因的吸附量随比表面积的增大而增加,树脂表面性质影响较小;但对儿茶素EGCG的吸附树脂表面性质影响较大,非极性吸附树脂X-5的吸附量最小,带有羰基和酰胺基的RB树脂吸附容量和吸附选择性较高,可将儿茶素EGCG和咖啡因层析分离开。

关键词: 儿茶素EGCG, 咖啡因, 吸附树脂

Abstract:

The performance of adsorption for catechins EGCG and caffeine by three resins with different surface properties were investigated in this study. The results showed that the adsorption capacity to caffeine rises with the increase of specific surface area and is little affected by the surface property. However, the adsorption capacity to catechins EGCG is significantly related to the surface property of resins. Nonpolar resin X-5 has the least adsorption capacity to catechins EGCG, while RB resin with carbonyl and methylactyl shows high adsorption capacity and strong adsorption selectivity to it, which can isolate catechins EGCG and caffeine by means of dynamic chromatography.

Key words: EGCG, caffeine, resin
