Abstract
The purpose of this study was to evaluate the antioxidant and free radical scavenging properties of anthocyanin extracts from three berries (Lonicera caerulea var. edulis,Vaccinium uliginosum Linn. and Rubus idaeus). The anthocyanins extracted were found to show remarkable scavenging activity on 2,2-Diphenyl-1-picrylhydrazyl (DPPH) radical, 2,2'-azinobis-(3-ethylbenzothiazoline-6-sulfonic acid) (ABTS) radical, hydroxyl radical (•OH) and superoxide anion radical (•O2-). The effect of these three anthocyanins on their reducing power increases in a dose dependent manner. The results obtained in the present study indicate that the three anthocyanins can be a potential source for natural antioxidant activity.
Key words: Anthocyanin, berry, free radical, antioxidant activity.
