A water-soluble polysaccharide, (Fr. II) isolated from aqueous extract of an edible mushroom Pleurotus sajor-caju, was found to consist of D-glucose, D-galactose, and D-mannose in a molar proportion of 1:1:1. Compositional analysis, methylation analysis, periodate oxidation study, partial hydrolysis, and NMR experiments ((1)H, (13)C, 2D-COSY, TOCSY, NOESY, HSQC, and HMBC) revealed the presence of the following repeating unit in the polysaccharide: [formula: see text] |
