Abstract
Aerial parts of Teucrium polium were subjected to headspace (HS) and hydro-distillation (HD)
techniques after drying, then headspace volatiles and the essential oil were analyzed by GC/MS. Forty-eight and
Thirty-nine constituents were identified in hydro-distillation and CombiPAL system which represented 99.7% and
99.8% of the oils, respectively. hydro-distillation method were α-pinene (30.8%), β- pinene (12.0%), myrcene (8.9%),
limonene (7.9%), (E)-caryophyllene (5.6%), Germacrene D (6.9%), Bicyclogermacrene (4.5%), α- Eudesmol (2.0),
valerianol (3.4%), and 7-epi-α-Eudesmol (3.2%) and the main compounds by CombiPAL techniques were α-pinene
(38.8%), β- pinene (15.5%), myrcene (21.0%), limonene (13.1%), and trans- β- ocimene (3.4 %). The Headspace
Technique is a new, rapid, simple and eco-friendly method for essential oil analysis of aromatic plants.
