Acetylated and non-acetylated flavonol triglycosides from Galega officinalis

Abstract

Three flavonol triglycosides kaempferol 3-[2(Gal)-(4- acetylrhamnosyl)robinobioside], kaempferol 3-(2(Gal)-rhamnosylrobinobioside) and quercetin 3-(2(G)-rhamnosylrutinoside) have been isolated from a methanolic extract of Galega officinalis aerial parts. They are reported for the first time in the genus Galega; moreover, the acetylated triglycoside is a new natural product.
