Essential Oil Content and Composition of Kelussia odoratissima Mozaff. as an Iranian Endemic Plant

The essential oil isolated by hydro distillation from aerial parts of Kelussia odoratissima was found to be a pale yellow liquid and was obtained in yield of 3.2 % (w/w) based on dry weight. The oil was analyzed by GC and GC-MS. Twenty-three compounds were identified, of which the major components were found to be Z-ligustilid (87.6 %), E-ligustilide (3.2 %), piperitone epoxide (3.1 %) and pentyl butanoate (1.7 %). The other constituents more than 0.5 % were: 2-methyl-1-octene-3-yne (0.6 %), (Z)-3-butylidene phthalid (0.6 %) and kessane (0.5 %). We can use of K. odoratissima as a potential source of Z-ligustilid.
