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 (1)H and (13)C 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.
经温和酸降解从肠炎沙门氏菌 O41 的脂多糖中获得 O-多糖，通过化学分析以及 1D 和 2D（1）H 和（13）C NMR 光谱确定了 O-单元的以下结构：-->2）-β-d-Manp-（1-->4）-α-d-Glcp-（1-->3）-α-l-QuipNAc-（1-->3）-α-d-GlcpNAc-（1-->其中 QuiNAc 代表 2-乙酰氨基-2,6-二脱氧葡萄糖。所建立的结构与肠炎沙门氏菌 O41 的 O-抗原基因簇一致，并对先前报道的基因功能进行了初步分配。
