Abstract
In this study, antioxidant potentials of persimmon peel extracted with different levels of ethanol (0 [DW], 50, 70, and 99%) were screened for their antioxidant activity at various concentrations. The persimmon peel extracted by 70% ethanol inhibited 89.82% of 1,1-diphenyl-2-picrylhydrazyl radical at 0.5 mg/mL and had β-carotene bleaching inhibition activity at values of 91.26%. superoxide dismutase-like activity and reducing power had the highest in persimmon peel extracted by 70% ethanol each at 0.5 mg/mL and 1 mg/mL and the lowest persimmon peel extracted by distilled water. These results provided that persimmon peel extracted by 70% ethanol could be the most effective as a natural antioxidant in food industry.
