摘要
Galactomannan with a molecular weight of 1976 kDa was isolated by hot water extraction from the locoweed (Oxytropis lanata (Pallas) DC) seeds (yield, 3.68% of the seed weight); its solutions display high viscosity: [η] = 1697.7 ml/g and optical activity αD + 76.8°. The polysaccharide consists of mannose and galactose residues at a molar ratio of 1.36: 1. The backbone of galactomannan macromolecule is formed by 1,4-β-D-mannopyranose residues, 73.5% of which are substituted with single α-D-galactopyranose residues at C-6.
