摘　　要：研究了γ-亚麻酸的后处理方法及测定前样品的预处理,包括菌丝体干燥方式对菌体得率和γ-亚麻酸(GLA)含量的影响,低温结晶法浓缩纯化油脂中的GLA及样品预处理对测定结果的影响。The post-processing and the pretreatment of sample before analysis of γ-linolenic acid （GLA） produced by Mortierella ramanniana were studied, including the effects of drying methods on the yield of dried biomass and the composition of GLA in the lipid, GLA enrichment from lipid by low temperature crys tallization and the pretreatment of sample before analyzed by chromatography.
