Abstract:: Taking Fomitopsis ulmaria (Sor.:Fr.)Bond et Sing polysaccharides as the research object，the DPPH radical scavenging ability of the test method conducted elm Phellinus polysaccharide inhibitory effect and anti-oxidation were studied.The results showed that the inhibitory effect of the selected fungal inhibition zone does not appear on Escherichia coli and yeast minimal inhibitory concentration 2.250 mg/mL，the smallest of the four bacteria and Staphylococcus aureus associated suppression concentration of bacteria circle 4.500 mg/mL，the minimum inhibitory concentration of Bacillus subtilis was 9.000 mg/mL，research in anti-oxidation polysaccharide concentration in the range of 0.075—0.150 mg/mL DPPH radical scavenging capacity was not obvious，in with increasing concentration of polysaccharides significantly increased within the range of 0.150—0.600 mg/mL.
