The O-polysaccharide was isolated by hydrolysis of the lipopolysaccharide of Yersinia pseudotuberculosis O:2b, and studied by 1D and 2D NMR spectroscopy. The following structure of the polysaccharide was established: alpha-Abep. 1-->3. -->2) alpha-D-Manp-(1-->3)-alpha-L-Fucp-(1-->3)-beta-D-GalpNAc-(1-->. where Abe stands for 3,6-dideoxy-D-xylo-hexose (abequose).
通过水解假结核耶尔森氏菌O:2b的脂多糖分离出O-多糖，并采用一维和二维核磁共振光谱对其进行研究。确定了该多糖的以下结构：α-Abep. 1→3. →2)α-D-Manp-(1→3)-α-L-Fucp-(1→3)-β-D-GalpNAc-(1→。其中Abe代表3,6-二脱氧-D-木糖己糖（阿比可糖）。
