Abstract In this study root, leaf, inflorescence and seed flavonoids of 7 Amaranthus L. taxa are compared. Aqueous-ethanolic extracts of collected plant material were examined to practice flavonoid detection, isolation and identification by 2-dimensional paper chromatography, thin layer chromatography, UV spectroscopy and available references. Results showed all of examined taxa have flavonoid sulphate, flavon C & C-/O glycosides and aglycons in their root and aerial parts with the exception of leaves that had not aglycons. Isorhamnetin, Kaempferol, Quercetin and Rutin were found in all of studied taxa aerial parts. All of taxa roots had kaempferol, quercetin and rutin.
