Abstract

Analytical measurements and proton nuclear magnetic resonance (H-NMR) spectra of phenolic extracts have been performed on a set of Italian extra-virgin olive oils from different cultivars and geographical locations of Apulia region. Multivariate statistical analysis (Principal Component Analysis, Hierarchical Clustering Analysis and Discriminant Analysis) has been applied separately to analytical and NMR data.

Analytical parameters, in particular fatty acids compositions, permit the discrimination in terms of variety of the olive used while 1H-NMR data of phenolic extracts permit a classification according to the geographical origin of the samples.
