In vitro antioxidant effects of the methanolic extract of Mentha arvensis leaves were determined by both enzymic (CatalaseSuperoxide dismutase, Glutathione reductase, Glutathione-stransferaseand Glutathione peroxidase) and non enzymic (Ascorbic acid, α-Tocopherol, Polyphenols, Reduced glutathione, Flavonoids and Carotenoids) methods. Preliminary phytochemical screening revealed that the extract of the leaves of Artemisia niligirica possesses Tannin, Terpenoids, Alkaloids, and Flavonoids materials. The results obtained in the present study indicated that the Mentha arvensis might be a good source of natural antioxidant.
