Flavonoids from Ficaria verna Huds.

Abstract

A phytochemical investigation of the flowers and leaves of Ficaria verna Huds. (Ranunculaceae) yielded four additional known flavonoid compounds including: kaempferol 3-O-β-D(6″-α-L-rhamnopyranosyl)-glucopyranoside (nicotiflorin), apigenin 8-C-β-D-glucopyranoside (vitexin), luteolin 8-C-β-D-glucopyranoside (orientin) and apigenin 8-C-β-D-(2″-O-β-D-glucopyranosyl)-glucopyranoside (flavosativaside). The characterisation of these compounds was achieved by various chromatographic and spectroscopic methods (UV, 1H NMR, 13C NMR and MS).
