摘要：

An O-polysaccharide was obtained by mild acid degradation of the lipopolysaccharide of Salmonella enterica O41, and the following structure of the O-unit was determined by chemical analyses along with 1D and 2D H-1 and C-13 NMR spectroscopy: -> 2)-beta-D-Manp-(1 -> 4)-alpha-D-Glcp-(1 -> 3)-alpha-L-QuipNAc-(1 -> 3)-alpha-D-GlcpNAc-(1 -> where QuiNAc stands for 2-acetamido-2,6-dideoxyglucose. The structure established is in agreement with the O-antigen gene cluster of S. enterica O41 and tentative assignment of the gene functions reported earlier. (C) 2010 Published by Elsevier Ltd.
