| Abstract: | A water-soluble galactomannan, isolated from the seeds of Cassia alata Linn, has been investigated by using methylation analysis, periodate and CrO3 oxidation, n.m.r. spectroscopy, and reaction with Bandeiraea simplicifolia lectin and an α-d-galactosidase. The polysaccharide is composed of heptasaccharide units joined by β-(1→4) linkages. The polysaccharide has a molecular weight of 26,400, corresponding to ∼23 units. |
