A water-soluble fucoglucan, isolated from alkali-treated edible mushroom, Termitomyces robustus, consists Of L-fucose and D-glucose in a molar proportion of 1:4. Structural investigation of the polysaccharide was carried out by using total hydrolysis, methylation analysis, and periodate oxidation followed by GLC-MS, and the final structure was determined using NMR experiments (H-1 C-13, DQF-COSY, TOCSY, NOESY, ROESY, HMQC, and HMBC). On the basis of the above experiments it is concluded that the following repeating unit is present in the polysaccharide: [GRAPHICS] (c) 2008 Elsevier Ltd. All rights reserved.
