Plant gums of the Genus Sterculia. Part IV. Acidic oligosaccharides from Sterculia urens gum
Journal of the Chemical Society C: Organic Pub Date: DOI: 10.1039/J39700002256
Abstract
The acidic oligosaccharides formed on partial depolymerisation of Sterculia urens gum have been further examined. Previously uncharacterised oligosaccharides include 4-O-(α-D-galactopyranosyluronic acid)-D-galactose, O-(galactopyranosyluronic acid)-(1 → 2)-O-rhamnopyranosyl-(1→ 4)-galactose, O-(galactopyranosyluronic acid)-(1 → 2)-O-rhamnopyranosyl-(1 → 4)-galacturonic acid, and 3-O-(glucopyranosyluronic acid)-galacturonic acid from partial acid hydrolysis, and O-galactopyranosyl-(1 → 2)-O-(galactopyranosyluronic acid)-(1 → 4)-galactose from partial acetolysis. The configuration of the glycosidic linkage in 2-O-(α-D-galactopyranosyluronic acid)-L-rhamnose has been confirmed by degradation to 2-O-α-D-galactopyranosylglycerol.
