Abstract
Essential oil content and composition of Mentha longifolia (L.) Huds. collected from five regions in south-west of Iran were determined. The essential oil isolated by hydro-distillation for 3 h using a Clevenjer-type apparatus and the oil was analyzed by GC and GC-MS. Essential oil content was varying from 1.39 to 4.05%. From 23 identified compounds, the major compounds were; Piperitenone oxide (7.41 to 59.67%), Pulegone (3.61 to 49.43%), 1,8–Cineole (7.25 to 24.66%), α-Terpineol (2 to 6%) and β-pinene (1.32 to 4.19%).
Key words: Mentha longifolia, essential oil, Pulegone, Piperitenone oxide, Iran.
