采用~(13)C核磁共振法测定和确定了小皮伞多糖中的大分子葡聚糖、葡甘聚糖等3种多糖的一级结构,这些结果与组成分析和甲基化分析结果是一致的,确定了毫克级直接用~(13)C核磁共振法分析和检测多糖结构的方法.
The primary structures of three kinds of polysaccharides, such as dextran and glucomannan, were determined and determined by ~ (13) C nuclear magnetic resonance. The results were in agreement with the results of composition analysis and methylation analysis Consistently, a method of directly analyzing and detecting the structure of polysaccharides by the ~ (13) C nuclear magnetic resonance method was established.
