Acetylated and Non-acetylated Flavonol Triglycosides from Galega officinalis.

Abstract

Three flavonol triglycosides kaempferol 3-[2Gal-(4-acetylrhamnosyl)robinobioside], kaempferol 3-(2Gal-rhamnosylrobinobioside) and quercetin 3-(2G-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.
