Abstract: The antioxidant activity of the apple pomace polyphenols (APPs)was evaluated employing various established in vitro model systems , such as reducing power method , scavenging hydroxyl radical method ,scavenging , 1 , 1-diphenyl-2-picrylhydrazyl radical (DPPH)method , peroxidation of polyunsaturated fatty acid from yelk lipoprotein induced by Fe2+ method , and -carotene linoleic acid assay system .APPs showed better reducing power than butylated hydroxytoluene (BHT) and tert-Butyl hydroquinone (TBHQ).APPs showed more scavenging hydroxyl radical activity compared with BHT and TBHQ , the I C50 (inhibitory concentration 50 %) being 522.4 mgL-1 .APPs showed more effective scavenging DPPHactivity than BHT and TBHQ , the IC50was15.8 mgL1 .Furthermore , APPs showed powerful inhibitory effects on peroxidation of polyunsaturated fatty acid from yelk lipoprotein induced by Fe2 + at all the tested concentrations, theIC50 being 126.4 mgL-1 .Besides , APPs also showed very good inhibitory effects on -carotene/linoleic acid assay system at all the tested concentration levels , theIC50being 25.2 mgL-1 [ Ch , 5 fig .11 ref .]
