Abstract
The genus Nepeta (Labiatae) with the common Persian name of “Pune-sa” includes 67 species in Iran and Nepeta schiraziana Boiss. is one of its endemic species. In this study, the stems, flowers and leaves of Nepeta schiraziana were collected from Sepidan region in north-west of Fars Province. The essential oils of stems, flowers and leaves of the plant were separately obtained by hydrodistillation and analyzed by GC and GC/MS. In each oils of the stem and flower, fourteen components were identified with 1,8-cineole (45.6% and 39.4%), germacrene D (17.4% and 15.8%), and β-caryophyllene (11.7% and 10.6%) as the main constituents, respectively. Furthermore, 1,8-cineole (38.5%), β-caryophyllene (14.2%), and caryophyllene oxide (11.7%) were the major components among the 18 constituents characterized in the leaf oil. As a result, 1,8-cineole was the dominant compound in the investigated oils while nepetalactone isomers reported in many Nepeta species, were not identified in Nepeta schiraziana.
