A simple and rapid method is described for the preparation of a marine oil fraction highly enriched in (n - 3) polyunsaturated fatty acids. Cod roe, containing lipid up to 15% of its dry weight, approximately 70% of which is phospholipid, was the starting material. Incubation of a concentrated aqueous extract of the roe with porcine pancreatic phospholipase A2 (EC was the key step in the procedure. Extraction of the freeze-dried reaction product with diethyl ether containing formic acid produced an oil in a yield of 1.0 g/100 g wet wt of starting roe. The oil contained over 95% as free fatty acids, with 20:5 (n - 3) and 22:6 (n - 3) accounting for up to 24 and 40%, respectively, of the total free fatty acids. The therapeutic use of the oil is mentioned.
