Fraction (PMEx-AH-B) of water-soluble polysaccharide, showing stimulating activity against macrophages, was isolated from mycelia of solid cultured Phellinus linteus by hot-water extraction, ethanol precipitation, and chromatography. Chemical characteristics of PMEx-AH- were as follows: carbohydrate content, 71%; monosaccharide composition, Man:Glu:Gal (9:64:27); molecular weight, 1-7x104; uronic acid content, 6.8%. Fundamental structure of PMEx-AH-B is deduced as B-(1$→6)-D-glucan with B-(1[xigh??Iow?]3)-D-glucosidic side chains based on methylation analysis.
