| Abstract: | In this paper, a water-soluble polysaccharides was extracted from Agrocybechg Fruit-body was studied and its elimination effect in vitro on the superoxide radicals O2 - was investigated. The results showed that the concentration of NaOH, extracting time and the ratio of the powder to the water were 0.77 mol/L, 2.71 h, 1:88.22,respectively, under which the extracting rate of the polysaccharide reached 2.950 %. Besides, the achieved water-soluble polysaccharide showed great elimination effect on O2- with the EC50 value being of 1.5 mg/ml. |
