Essential oil copmposition of Kelussia odoratissima Mozaff.

Due to side effects of chemical drugs, special attention is given to pharmaceutical plants recently. Mountainous celery with scientific name of Kelussia odoratissima Mozzaf., is one of the valuable pharmaceutical plants which is used in Iran seriously and is exposed to danger of extinction. This plant is indigenous of central Zagros Mountains (especially Chahar Mahal Bakhtiari province) and only has been observed in Iran. First, in order to consider the chemical constituents of this plant and discover its pharmaceutical characteristics, three ecotypes have been harvested. The ecotypes contained Kouhrang, Bazoft and Doaab Samsami ecotypes and samples were in 200 meter transact. In growth stage, samples were prepared for each ecotype and their essential oils were obtained by hydro-distillation. The essential oils were analysed by gas choromotography coupled with mass spectrometery and the major components of essential oils of three ecotypes were characterized. 24, 21 and 24 compounds were identified in the samples of Kouhrang, Bazoft and Doaab Samsami, respectively, which indicated 90.4%, 95.6% and 93.6% of total oils. Comparison of essential oils compositions showed the major compounds in all oils were Z-ligustilide, E-ligustilide, 3-n-butyl phthalide, kessane, spathulenol and globulol, which formed about 88.6% of them. The mean percentages of Z-ligustilide and butylidene phetalide in three ecotypes were 39.5% and 19.1%, respectively and these compounds totally presents 58.7% of the celery oil. Phetalid derivatives were 68.6% of celery oil.
