Mentha longifolia L., commonly known as wild mint, belongs to family Lamiaceae. The aim of this study was to identify the chemical composition of essential oil extracted from four ecotypes of Mentha longifolia L. grown wild (Shahreza, Chadegan, Isfahan, and Falavarjan) in Isfahan province (Central Iran). The essential oil was extracted by a Clevenger approach and analyzed using GC/MS. In the aerial parts of the plant were identified 26, 30, 22 and 25 compounds for Shahreza, Chadegan, Isfahan and Falavarjan ecotypes, respectively. The major constituents of the essential oil from the aerial parts of M. longifolia in Shahreza province were piperitenone oxide (26.71%), 1,8-cineole (20.72%), α-pinene (14.28%), pulegone (7.81%), sabinene (7.06%) and trans-caryophyllene (4.23%). The main compositions in Chadegan province were piperitenone oxide (29.13%), 1,8-cineole (28.84%), sabinene (9.05%), pulegone (8.97%) and α-pinene (6.31%). The main compositions in Isfahan province were pulegone (44.75%), 1,8-cineole (13.82%), 2-cyclohexen-1-ol, 1-methyl (8.49%), isopulegone (8.07%) and menthone (4.37%). In Falavarjan province the constituents were pulegone (33.39%), 1,8-cineole (29.79%), sabinene (11.23%) and isopulegone (7.28%).
