Mentha (Mint) is common named “poneh” belongs to Lamiaceae family and has used in traditional medicine for a long time. M. longifolia is one of the most important species of this genus and consists of seven varieties in Iranica Flora. Many researchers studied about identification and correlation between this species and environmental factors. By attention that environmental factors influence the composition of essential oils, so the aim of this study is to analyze the composition of the oil of Mentha longifolia growing wild in different areas of Northern parts of Iran. Based on our results, monoterpenes and sesquiterpenes are the most chemical compounds in this species. The major components were Carvon ( 1.1- 26.6%); 1,8-cineol (3.4- 11.2%); cis-piperitone oxide(1.59- 34.94%), Pulegone (14.96-31.25%); Menthone (2.8-15.05%) and iso- Menthone (0.96- 43.79%0. M. longifolia var. chlorodictya is reported as the best varity of this species can used in traditional medicine and breeding programs.
