摘要
本文研究了杏鲍菇多糖对多种体系的抗氧化活性 ,表明杏鲍菇多糖对自由基引起的亚油酸、菜油氧化以及离体肝脏组织的脂质过氧化均有一定的抑制作用。在Fe2 + 催化的亚油酸脂质过氧化体系中 ,0 5 %的添加量抑制率可高达 4 8 2 0 % ;在Fenton催化亚油酸酯质过氧化体系中 ,0 % %的添加量抑制率可高达 4 6 72 % ;在高温强制保存的菜油体系中 ,0 1%的添加量可明显抑制POV值的增加 ;在CCL4诱导的肝脏脂质过氧化体系中 ,也有一定的抑制作用。
The antioxidative activity of Pleurotus eryngii polysaccharide was studied here.The research showed that it could to some extent resist the oxidation of linoleic acid,rapeseed-oil and liver tissue produced by free radical.Catalyzed by Fe 2+ ,the linoleic acid oxidation could be resisted by 48 20% with an additional dosage of 0 5%;Catalyzed by Fenton ,that would be 46 72% with 0 5%;Reserved under high temperature,the value of POV could be apparently stopped from increasing with 0 1%.It could to a certain extent resist the oxidation of liver tissue produced by CCL 4.
