Abstract: Under the optimum conditions of pre-test, the mix-fatty acids were obtained by enzyme reaction. The optimum effecting factors in reaction to purify α-linolenic acid by urea clathrate were studied: temperature of urea clathrate: -10℃; time of urea clathrate precipitation: 24 hours and proportion of solvent; 1:3:6. The purity of α-linolenic acid was 87.2% and the yield of a-linolenic acid about 67.5%.
