Abstract
The structure of an acidic polysaccharide isolated from Abtorna august a root bark was determined by sugar and methylation analyses and high resolution H-1- and C-13-NMR spectroscopy. The main chain of the polys accharide was composed of 1,2-linked alpha-L-rhamnopyranose and 1,4- o r 1,3-lifiked alpha-D-galacturonic acid residues. The terminal beta-D- glucuronic acid residue was attached to the 3- and/or 4-position of th e alpha-D-galacturonic acid residue.
