The peptides derived from egg white proteins were fractionated on Sephadex G-25 gel filtration column and the fraction were obtained by Sephadex G-25 gel filtration chromatography and fraction 3 showed the highest antioxidant activity with a subfraction 3-1 and 3-2 showed higher DPPH radical scavenging activities and the DPPH radical scavenging rates at 3 mg/ml were 84.02% and 81.17%, respectively. According to RP-HPLC chromatogram subfraction 3-1 had a high homogeneous composition.
