A large number of certiﬁed samples (84) of Sicilian olive oils arising from the eight cultivars most represented in Sicily (Biancolilla,Cerasuola, Moresca, Nocellara del Belice, Nocellara Etnea, Oglialora Messinese, Brandoﬁno and Tonda Iblea) have been collectedand analyzed by HPLC/MS using an atmospheric pressure chemical ionization (APCI) source. The sample preparation is verysimple; in fact, the oil samples are diluted without any chemical derivatization. A following statistical data treatment by generaldiscriminant analysis (GDA) allows the determination of the olive oil cultivar. Furthermore, changes in the composition ofglyceridic components of the olive oils lead to easy discrimination between fresh oils and 1-year-old samples.
