Isolation of eicosapentaenoic and docosapentaenoic acids from natural sources as their methyl esters by adsorption and distillation techniques

Methyl eicosapentaenoate and docosapentaenoate were isolated by adsorption and distillation techniques from the highly unsaturated esters of beef adrenal lipids. Specific extinction coefficients were determined under two different conditions of alkali isomerization.
