چکیده انگلیسی
Three antioxidant peptides were purified from protein hydrolysate of croceine croaker (Pseudosciaena crocea) muscle prepared using pepsin and alcalase, and identified as Tyr-Leu-Met-Ser-Arg (PC-1), Val-Leu-Tyr-Glu-Glu (PC-2), and Met-Ile-Leu-Met-Arg (PC-3) with molecular weights of 651.77, 668.82, and 662.92Â Da, respectively. PC-1 exhibited the highest scavenging activities on DPPH (EC50 1.35Â mg/ml), superoxide (EC50 0.450Â mg/ml), and ABTS (EC50 0.312Â mg/ml) radicals, but PC-2 exhibited the strongest hydroxyl radical scavenging activity (EC50 0.353Â mg/ml) among the three peptides. PC-1 also showed effective inhibition on lipid peroxidation in the model system. The good activities of isolated peptides might be benefit from the smaller size and hydrophobic and/or aromatic amino acids within their sequences.
