- Abstract
This study was carried out to determine the antioxidant and antidiabetic activities of Elaeagnus angustifolia L. (oleaster) fruits and leaves. The total phenolic, total flavonoid and tannin contents, antioxidant activities (DPPH and ABTS methods), and inhibitory effects against α-glucosidase and α-amylase enzyme were investigated in the oleaster fruit and leaf extracts obtained with methanol: water (1:1, v/v). In addition, lipase inhibition activity was determined in these extracts. The values in which the fruit and leaves of oleaster inhibit the α-glucosidase enzyme by 50% (IC50) were determined as 17.11 μg/mL and 124.71 μg/L, respectively. Neither fruits nor leaves displayed a lipase inhibition activity. In terms of the phenolic, flavonoid and tannin contents and antioxidant activity values of the extracts of fruits and leaves, the bioactive content of fruits was significantly higher than that of leaves (p<0.05). Considering in vitro antidiabetic activities of the fruits and leaves of oleaster, the consumption of these natural extracts may have a potential for the treatment of type 2 diabetes.
