摘要

采用尿素包合法从亚麻中纯化亚麻油以提高α-亚麻酸含量.利用响应面分析法对尿素包合法纯化α-亚麻酸工艺条件进行了优化.实验表明，最佳的包合反应条件为混合脂肪酸、尿素、无水乙醇的质量比是1∶3∶7，包合温度为-20 ℃，包合时间为30 h，此时α-亚麻酸的质量分数为9327%.本方法简便易行，可以为新药开发与工业化生产提供依据.

Abstract

Urea was employed to increase α-linolenic acid content of linseed oil. Conditions for Urea purifying α-linolenic acid process were optimized by using response surface analysis. Experimental results show the best conditions for it are as follows: the inclusion reaction mixture of fatty acid

urea

ethanol(quality than)= 1∶3∶7

the inclusion temperature is -20 ℃

and the inclusion time is 30 hours

when α-linolenic acid content is 93.27 %. The method is feasible for the development of new drugs

providing the basis for industrial production.
