The gum from Anadenanthera colubrina consists mainly of a complex high-arabinose heteropolysaccharide with a (1-->3)-linked beta-D-Galp main-chain and many different side-chains. These contain beta-D-Galp-[(1-->6)-beta-D-Galp]m-(1-->6)-, substituted in turn at O-3 by alpha-L-Araf-[(1-->3)-alpha-L-Araf-]0-2. Also present are (1) main-chain units substituted at O-4 and O-6 by alpha-L-Araf units, (2) side-chains of Rhap-(1-->4)-beta-D-GlcpA-(1-->6)-beta-Galp-groups, (3) alpha-L-Arap non-reducing end-units linked (1-->6) to D-Galp, and (4) beta-Araf and beta-Arap structures. For the first time, a plant gum exudate was found to contain in the natural state, reducing low M(r) carbohydrates. These were rhamnose (0.6%), arabinose (4.7%), mannose (0.1%), galactose (0.8%) and many oligosaccharides (0.6%; 11 with different RFs, with the majority containing arabinose). They were all mixtures with the exception of alpha-Rhap-(1-->4)-beta-D-GlcpA-(1-->6)-alpha beta-Gal and an incompletely identified hexasaccharide, probably having alpha-L-Araf-(1-->4)-beta-D-Galp- and -alpha-L-Araf-(1-->3)-beta-D-Galp- structures. The mono- and oligosaccharides do not appear to arise via in situ autohydrolysis of the gum.
