摘要
对酶法合成的葡萄糖基(α-1→6)β-环糊精的红外(IR)光谱、质谱(MS)、氢谱(1H-NMR)、碳谱(13C-NMR)、氢氢相关谱(1H1-H COSY)、氢氢完全相关谱(1H1-H TCOSY)、异核单量子相干相关谱(HSQC)和异核多键相关谱(HMBC)进行了解析报道,对所有的1H-NMR和13C-NMR谱进行了归属,讨论了红外特征吸收峰所对应的官能团的振动形式。
Glucosyl (α-1→6)β-cyclodextrin was synthesized by enzymatic method. The infrared spectrum(IR), mass spectrometetry (MS), ^1H nuclear magnetic resonance (^1 H-NMR ),^13 C nuclear magnetic resonance(^13 C-NMR),^1H-^1 H correlated spectroscopy(^1 H-^1 H COSY), ^1H-^1 H total correlated spectroscopy(^1 H-^1H TCOSY), ( ^1H detected ) heteronuclear single quantum coherence (HSQC), and ( ^1H detected ) heteronuclear multiple bond coherence (HMBC) of Glucosyl(α-1→6)β-cyclodextrin were investigated and interpreted. All the ^1H-NMR and ^13C- NMR chemical shifts were assigned by means of ^1H-^1H COSY , ^1H-^1 H TCOSY , HSQC and HMBC. The vibrations of functional groups of this compound were also discussed.
