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.

Summary
Extra virgin olive oil (EVOO) is considered the healing oil due to its essential nutrients. Fatty acid plays important parameter in the chemical of EVOO which has a high content of fatty acids, for example oleic acid ranging from 56 % to 84 % [9] Another important parameter is the sterol profile which is considered as a fingerprint to examine its geographic originality in the EVOO. There is not any research on the effect of the geographical location on the chemical characterization of the Memecik variety which cultivated in the southwest of Turkey and has a high oil content. A few researchers have focused their attention on geographical location of olive tree crops and how it may reveal its effect on physical, chemical properties of EVOOs. The characterization of geographical indication studies related to EVOOs have not been published on literature in Turkey. Propose of this study is to determine the effect of Memecik olive oils in different locations (Acarlar, Gökçealan, Sultaniye, Şirince, Zeytindağ, Havutçulu) and show differences on geographical locations while taking geographical indication label
