Chemical Constituents of the Essential Oil of Ajuga austro-iranica Rech. f. (Lamiaceae) from Iran

Abstract The essential oil of Ajuga austro-iranica Rech. f. growing wild in the Fars province of Iran was obtained by hydrodistillation and analyzed by GC and GC/MS. Thirty-nine components representing 91.5% of the total oil were identified. The main components of the oil were trans-verbenol (7.0%), caryophyllene oxide (6.8%), 6,10,14,-trimethyl-2-pentadecanone (6.5%), myrtenol (6.3%), 1-octen-3-ol (6.2%) and β-pinene (6.1%). Pinene type monoterpenes were dominant by constituting 30.5% of the total oil.
