| 摘 要： | 采用氯磺酸-吡啶法合成猕猴桃果水溶性多糖硫酸酯,对试剂比例、反应温度和反应时间等因素对取代度的影响进行了研究,并用体外试验观察了多糖硫酸酯对超氧阴离子、羟自由基、DPPH的清除作用以及对H2O2诱导的红细胞氧化溶血和大鼠肝匀浆脂质过氧化的保护作用,结果表明猕猴桃果水溶性多糖硫酸酯具有显著的体外抗氧化活性。

| Abstract: | Polysaccharide in Actinidia chinensis Planch.fruit was sulfated with chlorsulfonic acid-pyridine.Reagent proportion,reaction temperature,and reaction time were studied with substitution degree.Vitro scavenging activities of fucoidan on superoxide radical,hydroxy1 radical and DPPH,and its protective effects on H2O2 induced hemolysis of rat erythrocytes and lipid per-oxidation of liver homogenate in rat were investigated in this study.Sulfated polysaccharide shows significant antioxidant activity in experiments in vitro. |
