Abstract:
:Oxygen radical absorbance capacity (ORAC) is a widely used hydrogen atom transfer-based method which measures the antioxidant capacity of natural products. ORAC values of oleaster (Elaeagnus angustifolia L.), which was extracted with ethanol/acetone (7:3, v/v), ethanol/water (1:1, v/v) and methanol/water (1:1, v/v) in order to evaluate the effects of solvent type on antioxidant capacity, were examined. In general, results revealed that ethanol/water extracts exhibited better antioxidant capacity values. Furthermore, results obtained by using ORAC-eosin y (ORAC-EY), one of the widely used derivative of fluorescein (FL), as a fluorescent probe were compared with those obtained by using ORAC-FL. According to the results, ORAC-EY values were found to be compatible with ORAC-FL values.
