The methanolic extract of Artemisia incisa Pamp. was dissolved in distilled  water and successively partitioned with n-hexane, chloroform, ethyl acetate  and n-butanol. The antioxidant potential of all these fractions and remaining  aqueous fraction was evaluated by four methods, i.e., the scavenging activity  of the 1,1-diphenyl-2-picrylhydrazyl radical (DPPH), the total antioxidant  activity, the ferric reducing antioxidant power (FRAP) assay and the ferric  thiocyanate assay. In addition, the total phenolics was determined. The  obtained results revealed that among the studied fractions the ethyl acetate  soluble fraction showed the most potent DPPH-radical scavenging activity with  an IC50 value of 5.3 ± 0.71 μg mL-1, which is even more effective than the  standard antioxidant butylated hydroxytoluene (BHT) (IC50 value 0f 12.1± 0.92  μg mL-1). The ethyl acetate fraction also showed the highest FRAP value  (3677.13 ± 27.1 μg TE mL-1), inhibition of lipid peroxidation (60.93 ± 0.84 %  at 500 μg mL-1) and total phenolic content (95.5 ± 0.05 μg GAE g-1) as  compared to other fractions. However, the remaining aqueous fraction was  found to posses the highest antioxidant activity of all the fractions
