NMR and MALDI-TOF analysis of a water-soluble glucan from an edible mushroom, Volvariella diplasia.
A polysaccharide (Fr. II) has been isolated from the hot aqueous extract of the fruit bodies of an edible mushroom, Volvariella diplasia. The polysaccharide contains glucose only. On the basis of total acid hydrolysis, methylation analysis, NMR studies ((1)H, (13)C, 2D-COSY, TOCSY, NOESY, ROESY, HMQC, and HMBC), and MALDI-TOFMS analysis, the structure of the repeating unit of the polysaccharide was established as formula see text.
