Hashem Akhlaghi

The essential oil obtained by hydro distillation in a Clevenger-type apparatus of the aerial parts of Eremostachys macrophylla Montbr & Auch, grown wild in Iran, was analyzed by GC/MS. Forty-four compounds representing 91.6% of aerial parts oil of Eremostachys macrophylla were identified. The main components of the oil were hexadecanoic acid (27.5%), ethyl linoleate (8.5%), 6-methyl-α-ionone (8.0%), isobutyl phthalate (5.8%), α-cadinol (4.7%) and germacrene D (4.3%). The oil was rich in nonterpenoids (56.0%) and among them; oxygenated nonterpenes (53.2%) predominated over nonterpene hydrocarbons (2.8%).
