Abstract: Herein, we show that easy ambient sonic spray ionization mass spectrometry in the negative ion mode [EASI(-)-MS] of water: methanol extracts of olive oil samples from 5 different countries (Portugal, Italy, Spain, Lebanon, and Greece) provides very characteristic profiles of chemotaxonomic markers, that is, free fatty acids and phenols. These EASI(-)MS fingerprints, acquired with great speed and simplicity after minimal sample preparation, permits secure identification of the samples as olive oils via their unique profiles of fatty acids plus phenolic constituents as well the certification of geographical regions via characteristic features of the profiles of phenolic constituents.
