【摘要】 通过体外胰蛋白酶对刺参蛋白作用,研究其水解液所具有的抗氧化活性。通过测定刺参蛋白水解液清除DPPH(二苯基苦基苯肼)自由基、Feton体系产生的羟基自由基和邻苯三酚自氧化体系产生的超氧阴离子自由基的能力,研究刺参蛋白水解液抗氧化活性。结果表明,刺参蛋白胰蛋白酶水解液具有体外抗氧化活性。更多还原

【Abstract】 The antioxidative activity of trypsinized proteins from Stichopus japonicus was studied in vitro.Scavenging effects on DPPH radical,hydroxyl radical（·OH） produced from Feton system and superoxide anion radical（O₂） produced from the self oxidation method of pyrogallol were measured.The results showed that trypsinized proteins from S.japonicus had a strong radical scavenging activity in vitro.更多还原
