Abstract:
Complete 1H and 13C NMR assignments are described for two known oleanane glycosides, 3-O-beta-D-glucopyranosyl(1-->3)-beta-D-glucopyranosyl-28-O-beta-D-glucopyranosyloleanolic acid and 3-O-beta-D-xylopyranosyl(1-->2)-beta-D-glucopyranosyl-28-O-beta-D-glucopyranosyl oleanolic acid isolated from the methanol extract of the leaves of Diploclisia glaucescens.
