摘要：

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-Glc pA-(1 --> and --> 2)-alpha-D-Man p-(1 --> units. Single branch units of beta-D-Xylp and alpha-D-Gal p are linked to the O-3 positions of Man p and a significant number of Glc pA residues.
