A Comparative Study on The Composition of The Essential Oil of Nepeta Menthoides Growing Wild in Northwest of Iran (Sabalan Mountains in Ardabil Province)
Keywords:
Nepeta menthoides, essential oil, 1,8-cineol, geranyl acetate, β-pineneAbstract
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.
