A water-soluble fucoglucan, isolated from alkali-treated edible mushroom, Termitomyces robustus, consists of L-fucose and D-glucose in a molar proportion of 1:4. Structural investigation of the polysaccharide was carried out by using total hydrolysis, methylation analysis, and periodate oxidation followed by GLC-MS, and the final structure was determined using NMR experiments (1H, 13C, DQF-COSY, TOCSY, NOESY, ROESY, HMQC, and HMBC). On the basis of the above experiments it is concluded that the following repeating unit is present in the polysaccharide: [Formula: see text].
从经碱处理的食用菌粗壮白蚁伞中分离出的一种水溶性岩藻葡聚糖，由摩尔比为1:4的L-岩藻糖和D-葡萄糖组成。通过全水解、甲基化分析、高碘酸盐氧化后进行气相色谱-质谱联用对该多糖进行结构研究，并使用核磁共振实验（1H、13C、双量子滤波相关谱、全相关谱、核Overhauser效应谱、旋转框架核Overhauser效应谱、异核多量子相干谱和异核多键相关谱）确定最终结构。基于上述实验得出结论，该多糖中存在以下重复单元：[化学式：见原文]
