摘要：

Two homogeneous galactomannans were isolated from the seeds of Retama raetam, and investigated by using methylation analysis, periodate and CrO3 oxidation, NMR. spectroscopy, and reaction with Bandeiraea simplicifolia lectin and -D-galactosidase. The polysaccharide had backbones of (1-->3)- and occasional (1-->4)-linked beta-D-mannopyranosyl residues, and side chains, at positions 6, of single alpha-D-galactopyranosyl groups. One of the polysaccharides also had a few non-reducing terminal D-mannosyl groups. (C) 2004 Elsevier Ltd. All rights reserved.
