Abstract

Three alpha-galactosides of D-pinitol: 1D-O-(alpha-D-galactopyranosyl)-(1-->2)-4-O-methyl-chiro-inositol, 1, 1D-O-alpha-D-galactopyranosyl-(1-->6)-O-alpha-D-galactopyranosyl-(1- ->2)-4-O-methyl-chiro-inositol, 2, and 1D-O-alpha-D-galactopyranosyl-(1-->6)-O-alpha-D-galactopyranosyl-(1-- >6)-O-alpha-D-galactopyranosyl-(1-->2)-4-O-methyl-chiro-inositol, 3, present in vetch seeds, were isolated, purified, and quantitatively determined using column and high-resolution gas chromatography. Their structures were established by (1)H and (13)C NMR 1D and 2D techniques.
