Abstract
Controlled acid hydrolysis of odoratan, the mucilage from Polygonatum odoratum DRUCE var. japonicum HARA rhizome, and of falcatan, the mucilage from Polygonatum falcatum A. GRAY rhizome, has led to the isolations of six oligosaccharides. Analysis of components, periodate oxidation, methylation and partial degradation studies provided the evidences that they are O-β-D-glucopyranosyl-(1→4)-D-mannopyranose, O-β-D-mannopyranosyl-(1→4)-D-mannopyranose, O-β-D-mannopyranosyl-(1→4)-D-glucopyranose, O-β-D-mannopyranosyl-(1→4)-O-β-D-glucopyranosyl-(1→4)-D-mannopyranose, O-β-D-mannopyranosyl-(1→4)-O-β-D-mannopyranosyl-(1→4)-D-mannopyranose, and O-β-D-mannopyranosyl-(1→4)-O-β-D-mannopyranosyl-(1→4)-O-β-D-mannopyranosyl-(1→4)-D mannopyranose.
