Abstract

Two homogeneous galactomannans were isolated from the seeds of Cassiu sericea and investigated by methylation analysis, periodate and CrO, oxidation, ‘H- and 13C-n.m.r. spectroscopy, and reaction with a-D-galactosidase. The polysaccharides had backbones of (l-+3)- and occasional (l-4)-linked p-r>-mannopyranosyl residues and side chains, at positions 6, of single a-D-galactopyranosyl groups. One of the polysaccharides also had a few non-reducing terminal mannosyl groups.
