Fig. (2) Representative data showing DPPH radical scavenging antioxidant activity (pattern) and ABTS radical inhibition percentage (solid) by ethanol extracts of juneberries in 2012(blue), 2013(red) and 2014(green). Data shown are means ± standard deviation (n=5 experiments). For comparison, positive controls (purple) quercetin dihydrate (pattern) for the antioxidant activity assay and Trolox (solid) for the ABTS radical inhibition assay are displayed in this plot.
