Determination of Content of γ-Linolenic Acid and Dihomo-γ-Linolenic Acid by Gas Chromatography

Wei-xia Gao

Abstract

An area normalization method of content determination of γ-linolenic acid and dihomo-γ-linolenic acid was set up.The sample treatment and chromatography condition of γ-linolenic acid and dihomo-γ-linolenic acid were similar. The time of appearance peak was difference. The experiment of recurring, precision and recovery showed: RSD of γ-linolenic acid was 1.51%, 1.89% and 0.98%. RSD of dihomo-γ-linolenic acid was 1.45%, 1.15% and 0.81%. The r value of correction analysis appeared very significant level. This area normalization method of content determination of γ-linolenic acid and dihomo-γ-linolenic acid was simple, rapid with lower error.
