Abstract:
Provided are: a composition containing 96-99 area % of eicosapentaenoic acid alkyl ester, the composition having an arachidonic acid alkyl ester content of 0.7 area % or less, and an eicosapentaenoic-acid-alkyl-ester mono-trans isomer content of 2.5 area % or less; and a method for producing a composition containing a high concentration of eicosapentaenoic acid alkyl ester, the method including performing precision distillation on a composition containing eicosapentaenoic acid alkyl ester, obtained by alkyl esterification of a raw material oil containing eicosapentaenoic acid, under a vacuum of 0.2 Torr or lower and a temperature of 190° C. or lower in the entire column, and performing a concentration treatment on the precision-distilled composition using chromatography.

Claim (Index 1):
An eicosapentaenoic acid alkyl ester-containing composition which, upon measurement by gas chromatography, comprises 96 to 99 area % of an eicosapentaenoic acid alkyl ester, wherein the composition satisfies at least one of the following (i)-(iii):\n (i) the content of a n-nonadecanoic acid (C19:0) alkyl ester is 0.1 area % or less, (ii) the content of an arachidic acid (C20:0) alkyl ester is 0.2 area % or less, and (iii) the content of an icosa-5,9,11,14,17-pentaenoic acid (C20:5 n-3(5,9,11,14,17)) alkyl ester is 0.2 area % or less.
