title: Phenolics profiles of olive fruits (Olea europaea L.) and oils from Ayvalık, Domat and Gemlik varieties at different ripening stages.
abstract: Phenolic compounds in olive fruit and oils obtained from Ayvalık, Domat and Gemlik olive varieties collected at different ripening periods were evaluated by High Performance Liquid Chromatography (HPLC). Gallic acid and p-cumaric acid were identified for Ayvalık and Domat at each period of ripening, respectively. In addition, gallic acid, p-cumaric acid, sinapinic and apigenin acids were detected in Gemlik olive fruit. Hydroxytyrosol, rutin, oleoropein, luteolin, tyrosol, vanilic acid and gallic acid in Ayvalık olive fruit in all ripening periods were determined. The tyrasol contents varied between 0.18 to 1.57mg/kg. Luteolin contents of olive oils ranged at the levels between 0.12 to 2.28mg/kg. In contrast, oils had the lowest syringic, p-cumaric, chlorogenic and ferulic acids. Vanillic acid contents of oils ranged between 0.08 to 2.38mg/kg.
