• In the process of fractionation of methylesters of cuttle fish fatty acids with urea in methanol, highly unsaturated fatty acid esters (I) were able to crystallize at 0°C in the form of urea adducts, but few percent of the total methylesters were used to fail to form adducts.<BR>Non-urea-adduct forming fractions (II) showed in almost cases lower iodine values and higher conjugated dien contents, compared with those of (I) and their absorption at 1395cm<SUP>-1</SUP> was scarcely found out.<BR>Through autoxidation at room temperature, highly unsaturated esters (I) changed by degrees their properties and turned into the similar materials with (II).<BR>NAF (II) is probably a changed product of (I) through autoxidation.
