Abstract
The present research is focused on the use of comprehensive 2-D GC (GC x GC) for the thorough elucidation of fatty acid (FA) profiles contained in vegetable oils; the samples analysed consisted of extra-virgin olive oil and refined hazelnut oil. The enhanced sensitivity and the formation of group-type patterns provided by GC x GC enabled the identification and quantification of both well-known and rather unexpected FAs contained in the lipid matrices. Peak assignment was, in most cases, supported by using pure standard compounds. Of particular interest was the identification of a series of odd-numbered FAs in both samples. The results attained to demonstrate the usefulness of GC x GC also for the analysis of supposedly low-complex samples. © 2008 Wiley-VCH Verlag GmbH & Co. KGaA, Weinheim.Pubblicazioni consigliate
