AB-8树脂吸附和分离红花黄色素

Study on Yellow Pigment Absorbing and Separating of Carthamus tinctorins L by AB－8 Resin

本文研究了用树脂吸附和分离红花黄色素，比较了五种树脂对红花黄色素的吸附。选用AB－8树脂作吸附剂，洗脱剂用80％乙醇，产品质量较传统法好，产品杂质少，色价高。AB－8树脂非常稳定，使用17次后其吸附率仅降低2.32％。

This article studied the yellow Pigment absorbing and separating of Carthamus tinctorins L with AB－8 resin.We compared five resins.The results showed that AB－8 resin had the best performance of absorbing on Carthamus thinctorins L yellow pigment.In the course of desorbing the absorbed Carthamus tinctorins L yellow pigment with 80％ethanol,AB－8 resin showed a fairly good character of stabilization.After using of 17 times,the absorption factor was only decreased by nearly 2.32％.
