中文摘要:以Vc为对照品,测定珍珠贝多肽对DPPH自由基、羟基自由基、超氧阴离子自由基和ABTS自由基的清除能力,研究珍珠贝多肽的体外抗氧化活性。结果表明:珍珠贝多肽对4种自由基均具有较强的清除作用,且清除率都随着质量浓度的增大而显著增加(p<0.05),剂量效应关系明显;珍珠贝多肽对DPPH自由基、羟基自由基、超氧阴离子自由基和ABTS自由基的IC50分别为3.23、2.23、9.74、0.25 g/L。珍珠贝多肽具备较高的抗氧化能力,为其抗氧化活性肽的开发利用提供理论依据。
外文摘要:The aim of this study was to investigate the antioxidant effects of pearl oyster polypeptides in vitro. The scavenging capacities of pearl oyster polypeptides on DPPH·, OH·, O2-· and ABTS· were assayed in contrast with Vc. The experimental results indicated that pearl oyster polypeptides had strong effect of scavenging on DPPH·, OH·, O2-· and ABTS·. The IC50 were 3.23, 2.23, 9.74 and 0.25 g/L, respectively. Moreover, with the increase of the concentration of pearl oyster polypeptides, the scavenging rate of DPPH·, OH·, O2-· and ABTS· increased significantly(p〈0.05) in a dose-dependent manner. Therefore, pearl oyster polypeptides had strong antioxidant capacity, and it provided a theoretical foundation for the development and utilization of antioxidant peptides.
