Abstract:

The ·OH, DPPH·and O2·free radical systems and Fe3+ reduction system were selected to assay the antioxidant activities of different concentrations of collagen peptides from chicken bone. Results indicated that the collagen peptides presented significant scavenging activity to all of the three free radicals. In a certain concentration range, the maximum scavenging rates to ·OH, DPPH· and O2· free radicals were 99.74%, 80.24% and 53.71%, respectively, and the corresponding IC50 values were 4.85mg/ml, 32.06 and 16.48 μg/ml respectively. Also, the collagen peptides showed the significant reduction activity to iron ions.

Key words: collagen peptide, chicken bone, free radical, antioxidant
