| 摘 要： | 糖链组成的高度多样化及组成单元本身的相似性,使得糖类化合物的分离纯化面临很大的困难,进而导致糖分子结构在很大程度上落后于蛋白质和核酸的结构研究。本论文将DOSY(diffusion ordered spectroscopy,扩散排序谱)应用于由D 葡萄糖和β 环糊精组成的混合物分析研究。结果表明该方法具有良好的结构分析效果,可以很好地研究混合物中单一组分的成分确定及结构表征,作为一种“NMR 色谱”技术具有良好的应用前景。

| Abstract: | Structures of carbohydrates are very much complex due to their multiple monosaccharide combinations and glycosidic linkages. Their isolation and purification are also difficult because of their structure similarity. Therefore, structure analysis of carbohydrate is limited and left far more behind that of proteins and nucleic acids. NMR (nuclear magnetic resonance) method of DOSY (diffusion ordered spectroscopy) has been used to analyze the mixture of D-glucose (D-Glc) and β-cyclodextrin (β-CD) in this paper. The results suggested that the so-called NMR chromatography can be successfully used as a routine and complement method in the analysis of oligosaccharide mixtures. |
