Abstract
The genus Hertia, belonging to the Compositae family, contains 12 species distributed all over South and North Africa and South Asia. The Iranian flora consists of only 2 shrubby species of Hertia distributed in the desert areas. In this study, Hertia intermedia (Boiss.) O. Kuntze was collected from Hezar Mountain, at an altitude of 2900 m, in Rayen area, Kerman Province, Iran during June 2010. Essential oils of leaves, stems and roots of the plant were separately extracted using hydrodistillation method and analyzed by GC and GC/MS. Seventeen components (97.6%) were identified in the leaf essential oil, with β-pinene (32.1%), α-pinene (14.6%), β-phellandrene (14.2%), and α-thujene (13.5%) as the main constituents. Also among the twenty-one identified compounds (94.2%) in the stem oil, α-pinene (38.4%), β-pinene (14.8%), and trans-verbenol (12.3%) were found to be the major components. Furthermore, α-pinene (51.2%), germacrene D (11.2%), and myrcene (10.4%) were the main constituents among the eight compounds (95.3%) characterized in the root essential oil. All three oils were highly rich in monoterpenes.
