Composition of the essential oils of Cyclotrichium straussii (Bornm.) Rech. f. and Phlomis pungens Willd. from Iran

The composition of the essential oils from two Labiatae species of Iran were analyzed by GC and GC/MS. beta-pinene (33.8%) and 1,8-cineole (14.7%) were the main components among the 18 constituents characterized in the oil of Cyclotrichium strausii representing 93.2% of the total components detected...

Description
Summary:The composition of the essential oils from two Labiatae species of Iran were analyzed by GC and GC/MS. beta-pinene (33.8%) and 1,8-cineole (14.7%) were the main components among the 18 constituents characterized in the oil of Cyclotrichium strausii representing 93.2% of the total components detected. Twenty-four compounds were identified in the oil of Phlomis pungens, representing 91.7% of the total oil with germacrene D (24.5%), bicyclogermacrene (14.1%), alpha- pinene (13.5%) and (E)-beta-farnesene (13.4%) as major constituents. The oil of C. straussii consisted of mainly monoterpenes, while in P. pungens oil sesquiterpenes predominated over monoterpenes.
