Two digalactosyl D-chiro-inositols and two trigalactosyl D-chiro-inositols, members of the fagopyritol A series and fagopyritol B series, were isolated from buckwheat (Fagopyrum esculentum Moench) seeds. Structures of the first three were determined by 1H and 13C NMR. Fagopyritol B2 is alpha-D-galactopyranosyl-(1-->6)-alpha-D-galactopyranosyl-(1-->2) -1D-chiro-inositol, and fagopyritol A2 is alpha-D-galactopyranosyl-(1-->6)-alpha-D-galactopyranosyl-(1-->3)- 1D-chiro-inositol. Fagopyritol A3, a… CONTINUE READING
