title: Essential oil compositions of two populations of Salvia samuelssonii growing in different biogeographical regions of Jordan.
abstract: The composition of the essential oils of flowering aerial parts of Salvia samuelssonii Rech. fil. (Lamiaceae Section Aethiopis), collected in two different biogeographical regions, has been analyzed. Samplel, collected in a Mediterranean-like region, "As-Subayhi", contains mainly monoterpenes (54.2%), sesquiterpenes (27.6%) and phenylpropanoids (10.5%), while sample 2, collected in the Irano-Turanian region, "Al-Adasiyyah", contains mainly phenylpropanoids (30.6%), monoterpenes (24.9%) and sesquiterpenes (21.2%). In Samplel, the most representative constituents were sabinene (21.5%), cis-chrysanthenyl acetate (20.8%), germacrene D (9.3%) and myristicin (5.9%), while in sample 2, myristicin (24.1%), sclareoloxide (6.3%), and germacrene D (5.7%) were main constituents. The rate of oxygenated derivatives in the Irano-Turanian sample was higher than the Mediterranean sample. Myristicin is an unusual constituent of Salvia species.
