Abstract
Background and aims: Kelussia odoratissima Mozaff. is an Iranian endangered endemic plant with a wide use in the Central Zagros region of Iran as spice and medicinal herb for inflammatory and cardiovascular purposes. The aim of this study was to assess the essential oil compositions of Birahgan ecotype of K. odoratissima in Chaharmahal and Bakhtiari province.
Methods: The aerial parts of K. odoratissima were collected from Birahgan ecotype and then dried. The essential oils were obtained by hydro-distillation and were analyzed by Gas Chromatography-Mass Spectrometry.
Results: Twenty-four compounds were identified, of which the major components were found to be Z-ligustilide (64.3%), 2-octen-1-ol acetate (12.0%), (Z)-3-butyldiene Phthalides (4.5%), menthyl acetate (3.0%), α-copaene (2.8%), δ-cadinene (2.2%), neo-menthol (1.6%), menthol (1.5%) and α-cadinene (1.5%). The group of Phthalides was included as Z-ligustilide, E-ligustilide, (Z)-3-Butyldiene Phthalides and (E)-3-Butyldiene Phthalides, which these compounds formed 70.10% of all identified components.
Conclusion: Like other ecotypes, the ecotype of Birahgan is a rich source of Z-ligustilide that can be used in the pharmaceutical industries.
