以环氧氯丙烷为交联剂,在非水介质中合成了一种新型β-环糊精交联聚合物,该聚合物在水中的溶胀能力适中,非常适合作为柱色谱固定相.对绿茶提取物的吸附研究表明,该聚合物不吸附绿茶提取物中的咖啡因,但能吸附儿茶素类多酚,而且表现出对表没食子儿茶素没食子酸酯的特殊高选择性.因此,该新型β-环糊精聚合物不但可以用于绿茶提取物脱咖啡因,而且可以用于纯化表没食子儿茶素没食子酸酯单体.

In nonaqueous medium, a novel crosslinked polymer of β-cyclodextrin was synthesized by using epichlorohydrin as a crosslinking agent. It can be used as stationary phase for column chromatogram due to its moderate swelling ratio in water. The adsorption behaviors of green tea extract onto the polymer were investigated by thin-layer chromatography. The results indicated that the polymer preferred to adsorb catechins rather than caffeine, and it showed especially high selectivity for epigallocatechin-3-gallate. So it could be used for decaffeination of green tea extract or purification of epigallocateehin-3-gallate.
