dc.description.abstract This work aims to evaluate the biological activity of aqueous extracts of an endemic species of the Sahara, it is Oudneya africana (Brassicaceae). The aqueous extracts are obtained by traditional modes of preparation (decoction, infusion and maceration). The results obtained showed that the decoction has the best performance values, total polyphenol flavonoids and condensed tannins that are 22.67 ± 2.13% respectively, 82.93 ± 4.88, 38.45 ± 1.29 mg ER / g and 97 ± 0,27mg EC / g PS while the infusion has the largest rate of phenolic acids which is of the order of 1.77 ± 009 mg EAC / g. Antioxidants activity was carried out by three methods: ABTS, DPPH and FRAP. Indeed, the best activity for all three methods is obtained with the decoction are (± 11036.61 270.76 microM AND / g) (1072.91 ± 51.10 microM AND / g) (1072.91 ± 51, 10 microM AND / g) respectively. As regards antibacterial activity, the various extracts have no inhibitory activity of bacterial growth of the three selected strains (Escherichia coli ATCC 25922, Proteus mirabilisATCCandMicrococcus luteusATCC).
