Fatty acid analysis of triacylglycerols: Preparation of fatty acid methyl esters for gas chromatography

摘要

A method to prepare fatty acid methyl esters was developed for fatty acid analysis of triacylglycerols by gas chromatography (GC). Triacylglycerols were mixed with methanolic CH3ONa in hexane containing a mid-polar solvent for 10 s at room temperature. Under these conditions, trioleoylglycerol was converted to methyl oleate with an average yield of 99.3%. This procedure gave reliable and reproducible data on fatty acid compositions determined by GC. (C) 2015 Elsevier Inc. All rights reserved.
