A Comparative Study on The Composition of The Essential Oil ofNepeta MenthoidesGrowing Wild in Northwest of Iran (Sabalan Mountains in Ardabil Province)

[摘要] Hydrodistillation of fresh aerial parts of Nepeta menthoides growing wild in northwest of Iran (Sabalan mountains in Ardabil province), yielded 0.12% (w/w) essential oil. GC/MS analysis allowed identification of 33 components, which made up 93.61% of the total oil. The main components of the sample were 1,8-cineol (38.68%), geranyl acetate (12.05%), β-pinene (7.8%), cinerolon (3.57%) and α-terpineol (2.94%). The oil was rich in oxygenated monoterpenes (61.14) predominated over monoterpene hydrocarbons (15.4%). Comparison of these results with those from previous studies shows large differences, suggesting significant environmental influences on oil composition.
