A C 20 fatty acid mixture (5.9 g), which was obtained from fractional distillation of 95 g methyl esters of rapeseed oil, was subjected to countercurrent distribution. This procedure yielded 4.5 g eicosenoic acid (20∶1), 0.4 g eicosadienoic acid (20∶2), and 0.04 g eicosatrienoic acid (20∶3), 4.7%, .42% and .04%, respectively, of the total methyl esters.
