Abstract The aim of this thesis is the quantification of phenolic compounds and the qualitative characterization of extra virgin olive oils samples from the area of Crete, and the correlation of the experimental data with the organoleptic characteristics of the olive oil, as measured by expert panels. The polar phase was initially isolated by extraction and total polyphenols were determined using a CDCl3 solvent containing an internal standard (DMT). The precise amount of DMT was determined using as standard oleic acid. This solvent was used while it's not reacting with the considered phenolic compounds. In addition, the repeatability of the experiments was examined. The analysis and quantification was achieved by using one-dimensional 1H nuclear magnetic resonance spectroscopy (1H NMR) at 500MHz. After initial processing of the obtained spectra, peaks were identified by comparison with standard 1H NMR spectra. The polyphenols were then integrated and quantified. Spectra were processed using Topspin-Bruker 4.0.7.
