Four oligosaccharides containing a fructopyranosyl residue have been found from fermented beverage of plant extract and isolated from the beverage using carbon-Celite column chromatography and preparative high performance liquid chromatography. Structure confirmation of the saccharides was provided by methylation analysis, MALDI-TOF-MS and NMR measurements. These saccharides were identified as oligosaccharides of fructopyranoside series; β-d-fructopyranosyl-(2→6)-d-fructofuranose (1), β-d-fructopyranosyl-(2→1)-d-fructopyranose (2), β-d-fructopyranosyl-(2→1)-β-d-fructofuranosyl-(2↔1)-α-d-glucopyranoside (3), and β-d-fructopyranosyl-(2→6)-α-d-glucopyranosyl-(1↔2)-β-d-fructofuranoside (4). Saccharides 3 and 4 among novel saccharides 1, 3, and 4 were named ‘pyrano-1-kestose (pyrano-isokestose)’ and ‘pyrano-neokestose’, respectively.
