Kidney vetch (Anthyllis vulneraria L.) is an old medicinal plant mostly known for ethnomedicine. Nowadays, its herbal parts are only scarcely used in phytotherapy, whereas medicinal applications of roots have not been reported so far. In this study, we investigated ethyl acetate (EtOAc) extracts obtained by solvent partition of an acetone/water crude extract of A. vulneraria roots. Mainly prenylated chalcones, flavones, isoflavones, and cinnamic acid derivatives dominated the compound profile when the extracts were studied by HPLC-ESI-(HR)MS
