Percent trygliceride composition, total carotenoids and chlorophylles and the main quality parameters of 110 and 29 extra-virgin oils most important Sardinian and Corsican production places, respectively, have been inspected. Statistical analysis of data revealed that some of the above cited components can serve as discriminatory factors to exactly define the origin of the oil, while others do not. On the other hand, some similarity has been found
with other components of the two islands. In particular, it has been found that an exact identification of place of origin is easily achieved for zones 2 (south Sardinia) and 3 (north-west Sardinia), because they show the significantly highest content of POL trygliceride and palmitoleic acid or SOO trygliceride and stearic acid, respectively. Moreover, zones 2 and 3 have the significant lowest content of OOO and PSO tryglicerides, respectively. A cross comparison of parameters allows the place of origin identification for the remaining zones as well.
A geographical discrimination of Corsican oils is possible only for those marked as AB, B and G, due to their significantly higher content of LLL, OLLn and PPO tryglicerides, with respect to the other places of origin. No statistical difference was found for S, Z and C oils.
