The content of the following isotopes of the 36 elements (Li7, Be9, B11, Na23,Mg24, Al27, P31, Ca39, Ti48, V51, Cr53, Mn55, Fe56, Co59, Ni60, Cu63, Zn64, Ga71, Ge74, As75, Se77, Rb85, Sr88, Mo95, Pd106, Ag107, Cd111, In115, Sn120, Sb121, Cs133, Ba137, Tl205,Pb206/207/208 and Bi209) in edible oils produced from twelve sunflower varieties from Republic of Macedonia were determined, using inductively-coupled plasma-mass spectrometry (ICP-MS) after microwave digestion, employing nitric acid and hydrogen peroxide in this step. The method has been validated using both an oil reference material and recovery experiments over different oil samples, obtaining satisfactory results in both cases. Interday repeatability lower than 10% was observed for all of the analyzed elements in the analyzed oil samples. Studying the multi-elements content, in order to detect tendencies in the oil samples between varieties, principal components analysis was used. Promising groupings were observed using a model with two principal components and retaining 82.3% of the variance.
