Constituents of the volatile oils of two teucrium species from Turkey

Abstract

The chemical composition of the essential oils of dried aerial parts of two Teucrium species were analyzed by GC and GC-MS. The essential oils of two Teucrium species were studied and eighty components, in all, were identified representing (90.8%) and (82.4%) of the oils respectively. The oil of Teucrium polium L. subsp. polium is characterized by the monoterpene b-pinene (10.2%) and the sesquiterpene germacrene D (10.1%), while that of Teucrium multicaule Montbret Et Aucher Ex Bentham had a higher contents of sesquiterpene caryophyllene oxide (31.1%). Quantitative and qualitative variations were determined in the essential oil composition of different parts of the studied plant. The high amount of monoterpenes α- and β-pinene and the sesquiterpene germacrene D, caryophyllene oxide make the studied taxon a privileged potential source for pharmaceutical, cosmetic and industrial products.
