The O-polysaccharide was isolated from the lipopolysaccharide of Echinicola pacifica KMM 6172(T) and studied by chemical analyses along with (1)H and (13)C NMR spectroscopy, including (1)H, (1)H COSY, 1D and 2D TOCSY, ROESY, (1)H, (13)С HMQC, HMBC and H2BC experiments. It was found that the polysaccharide is built up of branched pentasaccharide repeating units, containing D-galactose (Gal), L-rhamnose (Rha), 2-acetamido-2-deoxy-D-glucose (GlcNAc), two residues of 2,3-diacetamido-2,3-dideoxy-D-glucuronic acid (GlcNAc3NAcA) and O-acetyl group in nonstoichiometric amount and has the following structure [Structure: see text].
从太平洋艾氏菌KMM 6172(T)的脂多糖中分离出O-多糖，并通过化学分析以及¹H和¹³C NMR光谱进行研究，包括¹H、¹H COSY、一维和二维TOCSY、ROESY、¹H、¹³C HMQC、HMBC和H2BC实验。结果发现，该多糖由分支的五糖重复单元组成，包含D-半乳糖（Gal）、L-鼠李糖（Rha）、2-乙酰氨基-2-脱氧-D-葡萄糖（GlcNAc）、两个2,3-二乙酰氨基-2,3-二脱氧-D-葡萄糖醛酸（GlcNAc3NAcA）残基和非化学计量的O-乙酰基，其结构如下[结构：见原文]。
