[求助] 推荐多糖或者糖类物质核磁解析的相关书籍中英文均可已有3人参与

分析小硕在做多糖结构
但是现在有一堆核磁图不知如何下手去解看了许多文献还是不清楚
求推荐书籍或者有详解的文章

多糖结构分析方法还是以单糖鉴定+波谱分析为主，尤其是多种NMR技术联合。我就不详细阐述了，给您一篇综述文献看看。
A review of NMR analysis in polysaccharide structure and conformation: Progress, challenge and perspective
Abstract

Nuclear magnetic resonance (NMR) has been widely used as an analytical chemistry technique to investigate the molecular structure and conformation of polysaccharides. Combined with 1D spectra, chemical shifts and coupling constants in both homo- and heteronuclear 2D NMR spectra are able to infer the linkage and sequence of sugar residues. Besides, NMR has also been applied in conformation, quantitative analysis, cell wall in situ, degradation, polysaccharide mixture interaction analysis, as well as carbohydrates impurities profiling. This review summarizes the principle and development of NMR in polysaccharides analysis, and provides NMR spectra data collections of some common polysaccharides. It will help to promote the application of NMR in complex polysaccharides of biochemical interest, and provide valuable information on commercial polysaccharide products.
