Abstract

Ten flavonol glycosides were isolated from the EtOAc fraction of the MeOH extract of Metaplexis japonica Makino. Structures of the flavonoids were elucidated on the basis of spectroscopic data and comparison with literature values. The flavonoids were found to be mostly common flavonol 3-glycosides. It is of interest that the sacchaide parts of the isolates were pairs of arabinosides, glucosides, galactosides, rutinosides and robinobiosides of kaempferol and quercetin. All of these compounds were isolated for the first time from this plant.
