Abstract: 
Memecik olive oil variety which cultivated in six different locations were evaluated the effects of geographical locations on the chemical characterization of in the southwest of Turkey. The agricultural ecological map of each location was created using GIS. Olive oil samples were analyzed fatty acid, sterol and phenolic. Moreover, LC IMS QTOF spectrometer and Progenesis QI software were used to determine the geographical fingerprints of olive oil samples in different locations. Results showed that oil qualities of all locations differ significantly depending on olive growing area (p <0.05). The Principal Component Analysis of the different locations analyzed revealed that "geographical location" factor significantly affects the olive oil quality.
