Abstract

Abstract Incubation of cycloinulohexaose and methyl α- d-glucopyranoside in the presence of cycloinulo-oligosaccharide fructanotransferase gave some hetero-oligosaccharides. The main product was a tetrasaccharide whose sugar composition was methyl α- d-glucopyranoside- d-fructose in a ratio 1:3. This oligosaccharide was isolated from the reaction mixture by charcoal-column chromatography and was identified as methyl O-β- d-fructofuranosyl-(2 → 1)- O-β- d-fructofuranosyl-(2 → 1)- O-β- d-fructofuranosyl-(2 → 6)-α- d-glucopyranoside (methyl 6- O-β-inulotriosyl-α- d-glucopyranoside), by two-dimensional NMR spectroscopy. © 1997 Elsevier Science Ltd.
