摘要：
Fraction (PMEx-AH-beta) 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-beta were as follows: carbohydrate content, 71%; monosaccharide composition, Man : Glu:Gal (9:64:27); molecular weight, 1-7x10(4); uronic acid content, 6.8%. Fundamental structure of PMEx-AH-beta is deduced as beta-(1 -> 6)-D-glucan with beta-(1 -> 3)-D-glucosidic side chains based on methylation analysis.
