| Abstract: | The polysaccharide extracted from Stenoloma chusanum by hot water.The crude polysaccharide was isolated by DEAE-cellulose and Sephadex G-200 chromatography column in turn.This crude polysaccharide was tested for the efficacy against the phytopathogenic microorganisms and animal pathogenic bacteria using the agar disc diffusion method.The result showed： the crude polysaccharide have strong activities against gram positive phytopathogenic microorganisms and animal pathogenic bacteria.The minimum inhibition concentration（MIC） of polysaccharides against Helminthosporium turcicum Pass and Ustilagu Scitaminea Sydow were 5.0 mg/ mL. |
