In the present study, the chemical composition of the essential oils from the aerial parts of Teucrium fruticans L. collected in Sicily and Malta, Teucrium scordium subsp. scordioides (Schreb.) Arcang. and Teucrium siculum (Raf.) Guss., collected in Sicily, were eval- uated by GC-MS. The main volatile components of both T. fruti- cans collections were germacrene D (29.4% and 50.0%), (E)- b-caryophyllene (19.6% and 21.9%), and 1-octen-3-ol (19.7% and 7.4%); T. scordium subsp. scordioides essential oil was rich in car- yophyllene oxide (25.8%), a-pinene (19.4%) and b-pinene (8.5%); T. siculum essential oil was rich in (E)-b-caryophyllene (30.9%), 1- octen-3-ol (9.0%), a-humulene (8.6%) and germacrene D (8.0%). The chemotaxonomic relationship with other members of the respective botanical sections was discussed.

Abstract
In the present study, the chemical composition of the essential oils from the aerial parts of Teucrium fruticans L. collected in Sicily and Malta, Teucrium scordium subsp. scordioides (Schreb.) Arcang. and Teucrium siculum (Raf.) Guss., collected in Sicily, were eval- uated by GC-MS. The main volatile components of both T. fruti- cans collections were germacrene D (29.4% and 50.0%), (E)- b-caryophyllene (19.6% and 21.9%), and 1-octen-3-ol (19.7% and 7.4%); T. scordium subsp. scordioides essential oil was rich in car- yophyllene oxide (25.8%), a-pinene (19.4%) and b-pinene (8.5%); T. siculum essential oil was rich in (E)-b-caryophyllene (30.9%), 1- octen-3-ol (9.0%), a-humulene (8.6%) and germacrene D (8.0%). The chemotaxonomic relationship with other members of the respective botanical sections was discussed.File | Dimensione | Formato | |
