The neutral polysaccharides of the tuberous roots ofBiebersteinia multifida consist of three weakly branched glucans, A, B, and C. It has been established by periodate and chromic acid oxidation, methylation, and mass spectrometry that in the chains of glucans A, B, and C the monosaccharides are linked to one another by α-1 → 6 bonds and there is branching at the C-3 atoms of the glucopyranose residues.
