Abstract
Volatile oils obtained by hyrodistillation (HD) and solvent free microwave extraction (SFME) from the aerial parts of Ferula gummosa (Apiaceae) were analyzed by means of GC and GC-MS. A total of forty two compounds were identified in the hyrodistilled oil accounting for 96.5 % of the oil, of which γ-elemene (14.1 %), germacrene B (11.8 %), (E)-γ-bisabolene (10.7 %), viridiflorene (8.1 %) and epizonaren (6.2 %) were found to be the most abundant constituents. In the oil obtained by SFME, thirty nine natural compounds were recognized, representing 98.4 % of the chemical profile, with aromadendrene (17.6 %), germacrene B (16.2 %), γ-elemene (6.5 %), (E)-γ-bisabolene (6.3 %) and β-elemene (5.1 %) being the major components. Therefore, in both oils sesquiterpene hydrocarbons predominated over other compounds.
