This study aims to investigate phytochemical constituents of Pulicaria laciniata extracts and determine their antioxidant activity using three methods; Phosphomolybdate, Reducing Power, and Metal Chelating. The phytochemical investigation showed various secondary metabolites such as Phenols, Glycosides, Flavonoids, Alkaloids, Tannins, and Terpenoids. The N-butanol extract exhibited the highest antioxidant activity comparing with the other extract in all methods (0.51 and 0.65 mg/ml as A0.5 values of Phosphomolybdate, reducing power) and (1.65mg/ml for IC50 value of metal-chelating). In contrast, all the extracts showed week activity against the metal-chelating method.
