摘要：

H-1 NMR spectra of Gl-alpha-CD and Gl-beta-CD were recorded using a spectrometer equipped with a 21.6 T magnet. An ultra-high magnetic field was effective for detecting H-1 NMR signals with a small difference in chemical shifts. Introducing a glucosyl group onto CDs as a branch caused deformation of equilibrated H-1 signals of cyclodextrin. Particularly, H-1 signals in branched glucose were shifted greatly.
