Partial acid hydrolysis of water soluble Cassia glauca Lam. seeds polysaccharide afforded four oligosaccharides as: [I] 4-O-β-D-mannopyranosyl-(1→4)-O-β-D-mannopyranose, [II] 6-O-α-D-galactopyranosyl-(1→6)-O-α-D-mannopyranose, [III] 6-O-α-D-galactopyranosyl-(1→6)-O-α-D-mannopyranosyl-(1→4)-O-β-D-mannopyranose and [IV] 6-O-α-D-galactopyranosyl-(1→6)-O-α-D-mannopyranosyl-(1→4)-O-β-D-mannopyranosyl-(1→4)-O-β-D-mannopyranose. Oligosaccharides were characterized and identified by optical rotation, degree of polymerization, derivatives (disaccharides only), reduction with sodium borohydride, acid hydrolysis and periodate oxidation studies. These oligosaccharides results were corroborated the earlier proposed seeds polysaccharides structure of Cassia glauca Lam. plant.
