Essential Oil Content and Composition ofTeucrium arduiniL.

Abstract
Two samples of plant material of Teucrium arduini L., which were collected in 1989 and 1990 were hydrodistilled to produce oil yields of 0.07% and 0.18% (v/w) respectively. GC and GC/MS analysis revealed that germacrene D (23.4% and 57.8%) and β-caryophyllene (17.3% and 13.5%) were the main components of the oils.
