Volatile Constituents of Ballota aucheri Boiss.,Stachys benthamiana Boiss.and Perovskia abrotanoides Karel.Growing Wild in Iran

摘要

The composition of the essential oils from three Labiatae species of Iran-Ballota aucheri Boiss.,Stachys benthamiana Boiss.,and Perovskia abrotanoides Karel.-obtained by hydrodistillation were analyzed by GC and GC/MS.alpha-Cadinol(21.0%)and dehydroaromadendrane(11.8%)were the main components among the 37 constituents characterized in the oil of B.aucheri,representing 82.5% of the total components detected.Twenty compounds were identified in the oil of S.benthamiana,representing 91.2% of the total oil,with germacrene D(16.8%),linalool(16.6%)and beta-caryophyllene(11.0%)as the major constituents.The oil of P.abrotanoides was characterized by a higher amount of 1,8-cineole(28.0%)and camphor(24.0%),among the 23 components comprising 84.3% of the total oil detected:The endemic oils(B.aucheri and S.benthamiana)consisted mainly of sesquiterpenes,while in P.abrotanoides oil monoterpenes predominated.
