In this study, the ethyl acetate and n-butanol extracts of the north africa endemic species Tourneuxia variifolia Coss. Were used to evaluate the antioxidant activity using DPPH radical scavenging activity, ABTS+° decolorization, Cupric reducing power and reducing power in vitro essays and their phenolic content were also measured. The amounts of total phenolic and flavonoid contents were higher in ethyl acetate extract (979.5±3,53 mgGAE and 182±2.32 mgQE, respectively). However; EtOAc extract possessed a strong antioxidant activity in DPPH, ABTS and reducing power tests (IC50 =13.8±0.33; 5.18± 0.37; 23.85 ±2.88) whereas CUPRAC test (IC50 =204± 2.47µg/ml).
