Language eng - English Country NL - Netherlands Keywords LC-NMR ; fatty acids ; blackcurrant oil Subject RIV CI - Industrial Chemistry, Chemical Engineering R&D Projects GA203/04/0120 GA ČR - Czech Science Foundation (CSF) CEZ AV0Z40720504 - UCHP-M (2005-2011) AV0Z40550506 - UOCHB-X (2005-2011) Annotation While many naturally occurring mixtures of free fatty acids are conveniently analyzed by hyphenated technique of LC-NMR, a complete separation of alpha- and gamma-linolenic acids for their quantitative determination appears impossible at least by the methods of reversed phase HPLC. However, they can be differentiated and quantified from 1H NMR spectra measured in the course of isocratic acetonitrile–chloroform (90:10, with C8 and C18 columns in series) LC-NMR analysis without the need for any derivatization.
