Özet:

The genus Scutellaria L. (Lamiaceae) is represented by 39 taxa in Turkey. The ratio of endemism in Turkey is 43.6%. The chemical compositions of the essential oils obtained by hydrodistillation of Scutellaria galericulata and S. tortumensis from Turkey were analyzed by gas chromatography and gas chromatography-mass spectrometry, simultaneously. The main components were determined as caryophyllene oxide (27.5%), β caryophyllene (13.4%) and caryophylla-2(12),6-dien-5β-ol (4.8%) in the oil of S. galericulata. Germacrene D (29.8%), β caryophyllene (17.1%) phytol (8.3%) and nonacosane (7.1%) were found as major components in the oil of S. tortumensis. Overall, S. galericulata and S. tortumensis essential oils representing 88.6% and 94.3% of the total, respectively.
