Abstract

Sideritis genus is present by 46 species in Turkey with high endemism rate (ca. 82%). The chemical composition of essential oil obtained from the aerial parts of endemic Sideritis leptoclada O. Schwarz & P. H. Davis was investigated. The chemical composition of S. leptoclada from the Southern Turkey is reported for the first time by GCxGC-TOF/MS technique. Among the sixteen constituent representing 96.74% of the S. leptoclada oil, major components of S. leptoclada were found as α-pinene (24.84%), trans-β-caryophyllene (22.99%), β-pinene (15.14%) and caryophyllene oxide (6.65%). The results were discussed with the genus pattern in means of medicinal purpose and plant essential oils.
