From the flowers of Ficaria verna Huds. (Ranunculaceae), two flavonol triglycosides were isolated and their structures were elucidated by spectroscopic analysis (UV, NMR, MS) as 3-O-[_-L-rhamnopyranosyl-(1_6)-_-D-glucopyranosyl]-7-O-(_-D-glucopyranosyl) - quercetin (1) and 3-O-[_-L-rhamnopyranosyl-(1_6)-_-D-glucopyranosyl]-7- O-(_-D-glucopyranosyl) - kaempferol (2). In addition, the structure of 1 was determined using homo- and heteronuclear 2D NMR techniques.
