摘要: 本文研究了用树脂吸附和分离叶子花红色素,比较了4种树脂对叶子花红色素的吸附,在叶子花红色素提取过程中用AB-8树脂吸附,洗脱剂用40%的乙醇,洗脱效果好,且AB-8树脂使用20次后吸附性能仍稳定。

关键词: 叶子花红色素, AB-8树脂, 吸附

Abstract: This article studied absorbing and s eparating of the red pigment of Bougainvillea spectabilis Willd with AB -8resin .We compared the four resins.The results showed that four resins have the best performance of ab-sorbingtotheredpigmentof Bougainvillea spectabilisWilld.Inthecourseofdesorbingtheabsorbedredpigmentof Bougainvillea spectabilisWilld with40%ethanol,we selectedAB -8re sinduring the experiment.After using of20times,the absorption factor was very stabilization.

Key words: Bougainvillea spectabilis Willd red pigment, AB -8resin, absorbing
