摘要： A microbial oil comprising dihomo-γ-linolenic acid as a constituent fatty acid of an oil, the microbial oil has a content, in terms of a weight ratio of arachidonic acid relative to dihomo-γ-linolenic acid (arachidonic acid/dihomo-γ-linolenic acid) of less than 1/13. Preferably, the microbial oil has a triglyceride content of greater than or equal to 70% by weight, and a saturated fatty acid content of less than or equal to 40% by weight. Moreover, a lower alcohol ester of dihomo-γ-linolenic acid or a free fatty acid of dihomo-γ-linolenic acid obtained from the microbial oil is provided.

摘要： A method for producing monovalent unsaturated free fatty acids having 20 and/or 22 carbons or low-grade alcohol esters thereof, said method involving the following: obtaining free fatty acids or low-grade alcohol esters through the hydrolysis or alcoholysis of oils and fats derived from marine products; carrying out distillation on the free fatty acids or low-grade alcohol esters, and reducing the concentration of fatty acids with 18 or less carbons in the low-grade alcohol esters or free fatty acids; and collecting fractions of monovalent unsaturated free fatty acids having 20 and/or 22 carbons or low-grade alcohol esters thereof by column chromatography based on reversed-phase distribution.
