The use of the amaranths as vegetables is developed in Burkina Faso. Most known are Amaranthus
dubius Mart. Ex. Thell, Amaranthus graecizans L., Amaranthus hybridus L. and Amaranthus viridis L.
A. hybridus is most used and abundantly cultivated, however the others are more or less wild. Theaim of the
present study was to investigate the nutraceutical potentialities of four Amaranthus species from Burkina Faso.
The aqueous decoction extract of the four species contains the highest ofpolyphenols, flavonoids,flavonols and
proteins contents. The aqueous decoction extracts were used for the evaluation of the antioxidant activity and
xanthine oxidase inhibitory potentiality. The A. dubius showed the most potent antioxidant activity with a CE50
of 1.26±0.46, mgm2 the β-carotene bleaching method. A. hybridus showed the most potent antioxidant activity
(66.99±1.65 μmolAEAC/g) in the DPPH radical scavengingmethod. The aqueous extracts of the four
speciesshowed weak inhibition of the xanthine oxidaseat the concentration of 200 μg/mL.The four Amaranthus
species are rich in microelements (Na, K, Ca, Mg, P, Fe, Mn, Zn and Cu) and carotenoids compounds. The antinutritionals
factors were also quantified. The oxalate amount in these species is fairly high. The highest
minerals contents and the antioxidant activity of the amaranths could explain theirlarge use by all the socioeconomic
strata of the population.These plants would constitute a source of dietetic antioxidants.
Key words: Amaranthaceae, antioxidant activity, oxalate, phenolic and minerals content, xanthine oxidase, ,
