Abstract
The starting material for this study was a C 20- polyene fatty acid fraction obtained by high vacuum-distillation of the methyl esters of unsaturated acids from brain. This fraction was fractionated by counter current distribution when 3 main fractions were obtained. These fractions were subjected to ozonolysis, and the products identified bv column chromatography. The 3 fractions contained [DELTA]-5,8,ll,14-eicosatetraenoic acid, a mixture of [DELTA]-5,8,11- and [DELTA]-8,11,14 eicosatrienoic acid, and [DELTA]ll, 14_eicosadienoic acid.
