| 摘 要： | 以分离和提纯大豆异黄酮为目的 ,研究了AB 8、NKA 9,DM 30 1三种大孔吸附树脂对大豆异黄酮的吸附特性。结果表明 :AB 8树脂在低温下有利于对大豆异黄酮的吸附 ,3种树脂的平衡吸附量依次为AB 8>DH 30 1 >NKA 9。另外 ,AB 8树脂固定床的吸附穿透曲线表明 ,高浓度样液以较低的流速通过树脂层可以提高动态吸附的吸附速率。AB 8树脂对吸附的大豆异黄酮洗脱量大而且速度快 ,解吸容易 ,其次是DM 30 1树脂 ,而NKA 9树脂不仅洗脱速率低 ,而且耗费洗脱液。

| Abstract: | In order to separate and purify the soybean isoflavone,absorption equilibrium and kinetics of soybean isoflavone by using macro-pore resin AB-8,NKA-9,DM-301 were studied.The resin AB-8 exhibited good performance in absorbing isoflavone.The sequence of absorption of isoflavone were AB-8>NKA-9>DM301.When the AB-8 resin column absorbed isoflavone, better effects can be absorbed in the condition of higher concentration and lower elution rate.Eluting isoflavone from AB-8 was easily than other resins. |
