Abstract:

Galactomannan, a water-soluble heteropolysaccharide, was isolated from the seed of a Far Eastern population of the ground honeysuckle Lotus corniculatus L. (yield, 1.65%). Analysis of this galactomannan showed that it consists of D-mannose and D-galactose residues (molar ratio, 1.22 : 1). Its aqueous solutions were characterized by a specific rotation []_D = +84.1° and intrinsic viscosity [] = 559 ml/g. Analysis of this heteropolysaccharide using chemical and enzymatic procedures, as well as IR and ¹³C NMR spectroscopy, showed that its main chain comprises 1,4--D-mannopyranose residues, 95.5% of which are substituted at C-6 with single residues of -D-galactopyranose.
