Objective:To study the antioxidant properties of crude extract of different Asteraceae plants.Methods:The antioxidant properties of six extracts were evaluated using different antioxidant tests,including free radical scavenging,reducing power,metal chelation,superoxide anion radical scavenging,total antioxidant capacity and inhibition of lipid peroxidation activities.Results:Picris cyanocarpa(P.cyanocarpa)and Anthemis deserti(A.deserti)had powerful antioxidant properties as radical scavenger,reducing agent and superoxide anion radical scavenger while Achillia fragrantissima(A.fragrantissima)and Artemissia monosperma(A.monosperma)were the most efficient as ion chelator(100%at 100,200 and 400μg/mL)A.fragrantissima and Rhanlarium appoposum(R.appoposum.)showed 100%inhibition on peroxidation of linoleic acid emulsion at 200 and 400μg/mL,while butylatedhydroxy toluene and ascorinc acid showed 100and 95%inhibition percentage at 400μg/mL,respectively.Those various antioxidant activities were compared to standard antioxidants such as butylated hydroxyl toluene and ascorbic acid.Conclusions:In most tests P.cyanocarpa and A.deserti had powerful antioxidant properties as radical scavenger,reducing agent and superoxide anion radical scavenger.
