✦ Synopsis

High-resolution 13C NMR spectroscopy was used to study the potential of the method for the quantitative analysis of the most abundant fatty acids in the triacylglycerols of virgin olive oil samples harvested at di †erent geographic areas of Greece. The analysis of the results was compared with data obtained with gas chromatography. Both methods showed results that di †ered only by 1-2 mol% of the fatty acids. NMR data provided the a/b ratio of oleic and linoleic acids. The results showed a preference for the b-position in these unsaturated acids.
