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.
