Volatile Constituents of Teucrium persicum Boiss., Thymus caucasicus Willd. ex Ronniger subsp. grossheimii (Ronniger) Jalas. and Marrubium crassidens Boiss. Three Labiatae Herbs Growing Wild in Iran

Abstract The composition of the essential oils from the aerial parts of three Labiatae species of Iran: Teucrium persicum Boiss., Thymus caucasicus Willd. ex Ronniger subsp. grossheimii (Ronniger) Jalas. and Marrubium crassidens Boiss. obtained by hydrodistillation were analyzed by GC and GC/MS. epi-α-Cadinol (23.2%) and α-pinene (17.3%) were the main components among the thirty-one constituents characterized in the oil of Teucrium persicum representing 95.9% of the total components detected. Seventeen compounds were identified in the oil of Thymus caucasicus representing 99.6% of the total oil with thymol (34.2%), methyl chavicol (25.1%) and γ-terpinene (12.7%) as the major constituents. The oil of Marrubium crassidens was characterized by higher amount of β-caryophyllene (20.3%), germacrene D (12.9%), caryophyllene oxide (11.1%) and cubenol (11.0%) among the fourteen compounds comprising 91.7% of the total oil detected. The oils (Teucrium persicum and Marrubium crassidens) consisted mainly of sesquiterpenes, while in Thymus caucasicus oil monoterpenes predominated over sesquiterpenes.
