摘要
This article describes the application of silver ion solid-phase extraction (Ag+-SPE) to the separation of the fatty acid methyl esters (FAMEs) prepared from a partially hydrogenated fish oil (PHFO) with a trans fatty acid (FA) content of 41%. The complex FAME mixture was resolved into the following FAME fractions: saturated FA, trans-monounsaturated FA (trans-MUFA), cis-MUFA, and several polyunsaturated FA (PUFA) fractions with mixed geometric and positional isomers. Fractions were analyzed by gas chromatography (GC) using a 100 m cyanopropyl polysiloxane (CPS) coated capillary column. The GC analysis of the Ag+-SPE fractions allowed for the identification of the transand cis-MUFA and other FAME prepared from PHFO. © 2014 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.
