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.Urea was employed to increase et-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.
