The O-polysaccharide was obtained by mild acid degradation of the lipopolysaccharide of Providencia stuartii O47:H4, strain 3646/51. Studies by sugar and methylation analyses along with Smith degradation and 1H and 13C NMR spectroscopy, including two-dimensional 1H,1H COSY, TOCSY, ROESY and H-detected 1H,13C HSQC and HMBC experiments, showed that the polysaccharide has a branched hexasaccharide repeating unit with the following structure: [carbohydrate structure: see text]
O-多糖是通过对普罗威登斯菌O47:H4菌株3646/51的脂多糖进行温和酸降解获得的。通过糖分析、甲基化分析以及史密斯降解和1H和13C核磁共振光谱研究，包括二维1H,1H COSY、TOCSY、ROESY和H检测的1H,13C HSQC以及HMBC实验，表明该多糖具有一个具有以下结构的分支六糖重复单元：[碳水化合物结构：见正文]
