| Abstract: | Three non-reducing oligosaccharides were isolated from the fraction of cyclic (1→2)-β-d-glucan of Rhizobium meliloti J7017 by reversed-phase chromatography and paper chromatography. Methylation and 1H-NMR analyses indicated that they were α-d-glucopyranosyl α-kojitrioside, α-d-glucopyranosyl α-kojitetraoside, and α-d-glucopyranosyl α-kojipentaoside. |
