Abstract:
A non-ionic water soluble galactomannan made up of d-galactose and d-mannose was isolated from the seed endosperm of Cassia pleurocarpa. Acid catalyzed fragmentation, periodate oxidation, methylation and selective enzymatic hydrolysis revealed that the repeating unit of the heteropolysaccharide had a backbone of beta(1-->4) linked d-mannopyranosyl units to which D-galactopyranosyl units are linked as side chains through alpha(1-->6) linkages. The properties such as viscosity, water/saline retention, gelling behavior, and shelf life of the galactomannan indicated that the material may be exploited in biomedical applications for example drug delivery and tissue engineering fields.
