【摘要】 目的:研究裙带菜多糖及纯化产品的抗氧化活性。方法:采用超氧阴离子自由基体系、羟基自由基体系、烷基自由基引发的亚油酸氧化体系、二苯代苦味肼基自由基体系,对裙带菜多糖的抗氧化活性进行了研究,并同维生素C进行了比较。结果:裙带菜多糖对这几种自由基均有不同程度的清除作用,其对超氧阴离子、羟基自由基、烷基自由基有较强的清除能力;清除二苯代苦味肼基自由基能力较弱。结论:裙带菜多糖具有较强的抗氧化活性。更多还原

【Abstract】 Objective::To study the antioxidant activities of Undaria Pinnatifida polysaccharides and its purified product.Methods:Using the uperoxide radical system, hydroxy1 radical system,oxidation system of linoleic acid induced by alkyl radical and system of DPPH·,Studying and comparing the antioxidation activities of the Undaria Pinnatifida polysaccharides with Vitamin C.Results:The polysaccharide of Undaria pinnatifida exerts different degrees of scavenging effect on these radical systems,The scavening capability of Undaria pinnatifida polysaccharide to superoxide radical,hydroxyl radical and alkyl radical is strong but weak to DPPH·radical.Conclusion:The polysaccharide of Undaria pinnatifida has strong anti-oxidation activity更多还原
