摘要: 以低纯度的红车轴草异黄酮产品为原料,分别采用溶剂萃取法和静态吸附法进行分离纯化,并对分离纯化工艺的相关参数进行了系统研究。实验结果表明,在溶剂萃取法中,正丁醇:水溶剂体系的萃取效果明显好于乙醇双水相体系,比较适合于红车轴草异黄酮的初级纯化;静态吸附纯化法采用活性炭吸附杂质、氧化铝吸附异黄酮,甲醇:乙醚(1:1)混合溶剂为解吸附溶剂。该方法具有较高的分离纯化能力,可使产品纯度由22.6%提高到62.5%。

Abstract: The high purification isoflavone was extracted from low purification red clover isoflavone product by solvent extraction and static state adsorption.In this study,the factors by which influence to the purifying are studied systematically and deeply.The experiment results indicate that the purifying capability of n-Butanol/water was higher than aqueous two-phase.In the static state adsorption,activated carbon was used to impurity sorbents,alumina was used to isoflavone sorbents and the methanol/aether was used to release solvent.The experiment results indicate that the static state adsorption method have obvious purifying capability,the product purity was enhanced from 22.6% to 62.5% by using this method.

Key words: red clover isoflavone, isolate and purify
