flavonoid glycosides, kaempferol-3-O-α-L-rhamnopyranosyl-(1. 6)-β-D-glucopyranoside orkaempferol-3-O-rutinoside (1), isorhamnetin-3-O-α-L-rhamnopyranosyl-(16)-β-D-glucopyranoside or isorhamnetin-3-O-rutinoside (2), and quercetin-3-O-β . 2)-β-L-arabinopyranoside 3, the latter one being anew compound, were isolated from the methanolic extract of the aerial parts of Carrichtera annua. Massspectrometry and 1D and 2D NMR spectroscopy allowed establishing the structure of these compounds.KeywordsCarrichtera anua, Crucifereae (Brasicaceae), flavonol glycosides, NMR
