| Abstract: | A polysaccharide (PS),
isolated from the hot aqueous extract of the mushroom, Temlitomyces eurhizus,
is found to contain,
D-glucose, D-galactose,
D-mannose and D-galacturonic acid in a mole ratio of about 0.9:0.9:1.0:0.9.
From the peiiodate oxidation and methylation analysis of the PS, the linkages
among the constituent sugar residues are identified as, D-Galp (1,6 linked), D-Manp (1 ,2,3 linked), D-G1cp (1,3 linked) and D-galacturonic acid.
The anomeric configuration of the constituent sugar residues are determined by
the chromium trioxide oxidation studies of the acetylated polysaccharide. It is concluded that galactose
and mannose have the β-configuration while glucose and galacturonic acid have
the a-configuration. Based on the above observations, the structure of the
repeating unit of the polysaccharide was assigned as,
-6)- β-D-Galp-(1-3)- β-D-Manp-(1-3)- -D-G1cp-(1-
(2-1 )--D-GalpA |
