The oleaster (Elaeagnus angustifolia L.) plant grown in three different locations in Nevsehir, Turkey was analyzed to determine its phenolic component profile, total phenolic compound, total carotenoid, total flavonoid, and antioxidant capacity values. Ultrasonic extraction of the oleaster's flour, shell, core, flower, and leaf parts was carried out under solvent and acidic hydrolysis conditions using eight different polarity solvents (water, methanol, ethanol, acetone, ethyl acetate, butanol, petroleum ether, and hexane). The phenolic component profiles were determined using high-performance liquid chromatography with diode array detector (HPLC-DAD), and the main phenolic components in the oleaster samples were gallic acid, catechin, and their derivatives. At the same time, antioxidant properties of oleaster samples were evaluated by Folin-Ciocalteu (FC), ABTS, FRAP, DPPH, and CHROMAC methods. Various parts of oleaster, whose phenolic component content was determined in this study, are thought to be a natural source that can be used against degenerative diseases in future studies.
