A microbial oil comprises dihomo-γ-linolenic acid in fatty acid alkyl ester form and/or in free fatty acid form at a content of at least 50% by weight of the total weight of fatty acids in the oil. The content of thermally-produced fatty acid having from 16 to 22 carbon atoms, generated by heat associated with distillation in the production method, is from 0.0001% by weight to 3.0% by weight of the total weight of fatty acids in the microbial oil. A production method thereof comprises providing a starting oil containing dihomo-γ-linolenic acid in alkyl ester form and/or a free fatty acid form, obtained from microbial biomass; performing rectification of the starting oil under specific conditions; and obtaining the aforementioned microbial oil. Other aspects are a concentrated microbial oil, and use of the described oils as an agent for treating or preventing inflammatory disease.
一种微生物油包含脂肪酸烷基酯形式和/或游离脂肪酸形式的二氢-γ-亚麻酸,其含量至少占油中脂肪酸总重量的 50%(按重量计)。在生产方法中,通过蒸馏产生的热量产生的具有 16 至 22 个碳原子的脂肪酸的含量占微生物油中脂肪酸总重量的 0.0001%(按重量计)至 3.0%(按重量计)。其生产方法包括提供从微生物生物质中获得的含有烷基酯形式和/或游离脂肪酸形式的二氢-γ-亚麻酸的起始油;在特定条件下对起始油进行精馏;获得上述微生物油。其他方面是浓缩微生物油,以及将所述油用作治疗或预防炎症疾病的制剂。
