An O-specific polysaccharide containing D-galactose, D-mannose and L-rhamnose was obtained by mild acid hydrolysis of the lipopolysaccharide of the Salmonella Anatum bacterium. The structure of the polymeric O-antigen was studied by composition analysis and by 1D and 2D, 1H and 13C NMR spectroscopy. The repeating unit of the polymer was identified as a linear trisaccharide with the structure shown below, in which the galactose residue was partially O-ac ety lat ed at C-6; this was re spon si ble for the mol e cule’s structural heterogeneity. → 3)-D-Galp-(1𔾺)-D-Manp-(1𔾸)-alfa-L-Rhap-(1→ 6 OAc (75%).
