Abstract :The current work evaluated the chemical compositions of the essential oils insert ignore into journalissuearticles values(EOs); extracted from Mentha longifolia subsp . typhoides insert ignore into journalissuearticles values(Briq.); Harley var. typhoides PH. Davis, Mentha spicate L. subsp. spicata , Mentha longifolia insert ignore into journalissuearticles values(L.); Hudson subsp. longifolia and Mentha villoso nervata Opiz from gowning in the different locations of Tokat. The a ntioxidant activities of EOs were tested using total antioxidant activity, reducing power, inhibition of lipid peroxidation, metal chelating, H 2 O 2 , DPPH ˙ and O 2 ˙ - scavenging activities. The chemical compositions of EOs were determined by GC and GC-MS. Significant differences were recorded between the percentages of many constituents depending on the geographical. The most important components were identified consecutively: linalool insert ignore into journalissuearticles values(nd-62.80%);, menthone insert ignore into journalissuearticles values(0.31-60.81%);, pulegone insert ignore into journalissuearticles values(nd-21.52%);, isomenthone insert ignore into journalissuearticles values(nd-30.15%); and piperitoneoxide insert ignore into journalissuearticles values(nd-68.92%);. The inhibition of lipid peroxidation, O 2 ˙ - and H 2 O 2 scavenging activities of the EOs were very effective but their reduction power values were low. The results obtained validate that EOs of four Mentha species possess a source of antioxidant potential for medicinal and foods.
