MS/MS experiments were carried out in a triple-quadrupole instrument using multiple reaction monitoring mode in <2 min. The proposed method provided high fingerprinting power to identify the presence of five of the studied compounds in different types of vegetable oils (soybean, sunflower, corn, olive) with LODs at parts per billion levels. The method was validated, and different mixtures of extra virgin olive oil with seed oils were analyzed, achieving the typification for the detection of adulterations in extra virgin olive oils up to 2% w/w. The nonprotein amino acid ornithine was confirmed as a marker for adulteration in the olive oils analyzedThe projects involved in this work have been: project CTQ2009-09022 from the Spanish Ministry of Science and Innovation (Spain), project S2009/AGR-1464 from the Comunidad Autónoma of Madrid (Spain) and European funding from FEDER programme (ANALISYC-II), and project CCG10-UAH/AGR-5950 from the University of Alcalá and the Comunidad Autónoma of Madrid (SpainComunidad de MadridMinisterio de Ciencia e InnovaciónAmerican Chemical Society20122012-01-01journal articlehttp://purl.org/coar/resource_type/c_6501NAhttp://purl.org/coar/version/c_be7fb7dd8ff6fe43info:eu-repo/semantics/articleapplication/pdfhttp://hdl.handle.net/10017/21129https://dx.doi.org/10.1021/jf202857yreponame:e_Buah Biblioteca Digital Universidad de Alcaláinstname:Universidad de Alcalá (UAH)InglésengComunidad de Madrid http://dx.doi.org/10.13039/100012818 Not available CCG10-UAH ESMICIN Not available CTQ2009-09022 ESComunidad de Madrid http://dx.doi.org/10.13039/100012818 Not available S2009 ESopen accesshttp://purl.org/coar/access_right/c_abf2Attribution-NonCommercial-NoDerivatives 4.0 Internationalhttp://creativecommons.org/licenses/by-nc-nd/4.0/info:eu-repo/semantics/openAccessoai:ebuah.uah.es:10017/211292026-06-18T11:13:07Z
