## Abstract Seed galactomannans are vegetable, heterogeneous polysaccharides widely distributed in nature. Generally, they possess (1β4)βlinked Dβmannopyranose (Man) main chains to which are attached (1β6)βlinked Dβgalactopyranosyl (Gal) units. The Man/Gal ratios differ from gum to gum, resulting i
The endosperm of leguminous seeds is usually mucilaginous, and galactomannan is its main component. The seed polysaccharide of Cassia migera (N.O. Leguminosae). selected for structural investigations, contains 60% of endosperm. ## RESULTS AND DISCUSSION Galactomannan was isolated from the endosp
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>-mann
