Structural investigation of the polysaccharide fraction from the mucilage of Diceroaryum zanguebaricum Merr.
The polysaccharide fraction from the mucilage of Dicerocaryum zanguebaricum (Pedaliaceae) appears to be mainly constituted of a chemically homogeneous polysaccharide. By NMR and chemical degradative methods its structure appeared to consist of alternate-->4)-beta-D-GlcpA-(1--> and -->2)-alpha-D-Man p-(1-->units. Single branch units of beta-D-Xyl p and alpha-D-Gal p are linked to the O-3 positions of Man p and a significant number of Glc pA residues.
