Abstract
Carboxyl groups in Acaciasaligna (syn. cyanophylla) gum were reduced by reacting the gum propionate with diborane. Acetolysis of the reduced gum afforded a mixture of oligosaccharide acetates. After de-O-acetylation, 3-O-(α-D-galactopyranosyl)-L-arabinose, 3-O-(β-D-galactopyranosyl)-D-galactose, and 4-O-(α-L-rhamnopyranosyl)-D-glucose were isolated from the mixture. Keywords: acetolysis, Acacia gums.
