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.

Key words: Linseed oil; α-linolenic acid; Urea; experimental design of Response Surface Optimization.
