Zusammenfassung: | To provide a composition containing an alkyl ester of eicosapentaenoic acid and a method for producing the same.SOLUTION: A composition containing alkyl esters of eicosapentaenoic acid in an amount of 96 to 99 area%, in which alkyl esters of arachidonic acid are contained in an amount of 0.7 area% or less and monotrans-isomers of the alkyl esters of eicosapentaenoic acid are contained in an amount of 2.5 area% or less. And, a method of producing a composition containing a high concentration of alkyl esters of eicosapentaenoic acid, wherein the composition is obtained by subjecting an eicosapentaenoic acid alkyl ester-containing composition obtained by alkylating a feedstock oil that contains eicosapentaenoic acid, to precision distillation at a vacuum of 0.2 Torr or less and at a whole tower temperature of 190°C or less, and wherein the composition after the precision distillation is subjected to concentration treatment using chromatography.SELECTED DRAWING: None
