In this study, the antioxidative effects of Aronia melanocarpa fruit and leaf extracts were investigated. Thefree radical (1,1-diphenyl-2-picrylhydrazyl, DPPH) scavenging activities (FSC50) of the ethylacetate and aglycone fractionsof fruit extracts were 16.29 μg/mL, and 12.29 μg/mL, respectively. The free radical scavenging activity of fruitextract was higher than that of leaf extracts. Reactive oxygen species (ROS) scavenging activities (OSC50) of the ethylacetateand aglycone fractions of fruit extracts on ROS generated in Fe3+-EDTA/H2O2 system using the luminol-dependentchemiluminescence assay showed 2.86 μg/mL, and 1.80 μg/mL, respectively. ROS scavenging activity of the aglyconefraction of fruit extracts was similar to that of L-ascorbic acid (1.50 μg/mL). The ROS scavenging activity offruit extracts was higher than that of leaf extracts. The cellular protective effects of aglycone fraction of fruit extracts(τ50 = 72.3 min) on the1O2-induced cellular damage of human erythrocytes especially were increased in a concentrationdependent manner (5 ~ 50 μg/mL). τ50 (72.3 min) of the aglycone fraction showed 1.9 times higher than (+)-α-tocopherol (38 min), known as lipophilic antioxidant at 10 μg/mL. These results incidicate that A. melanocarpa fruitextracts have higher antioxidant effects than leaf extracts and could be applicable to functional cosmetics materials forantioxidants by protecting skin exposed to solar UV radiation against ROS including1O2.
