The quantitative analysis of the <sup>1</sup>H NMR helped in distinguishing the geographical origin of the olive oil samples. The intensity of <sup>1</sup>H NMR variables was submitted to the statistical method, analysis of variance (ANOVA). As a result of combining the NMR data and ANOVA, olive oils were discriminated based on regional origin rather than province. This less time consuming discriminative screening by <sup>1</sup>H NMR does not require any further analysis of the olive oil, including oxidative stability measurements or gas chromatography. The possibility of determining authenticity, even in an olive growing area of a small village was also shown. The two-dimensional (2D) non-invasive <sup>1</sup>H DOSY NMR experiment, known as “NMR chromatography”, was used to determine the olive oil sub-fraction.}, number={2}, journal={Grasas y Aceites}, author={Ok, S.}, year={2014}, month={Jun.}, pages={e024} }
