Composition of the essential oil of sideritis congesta P.H.Davis et Hub.-Mor.

Abstract

Water-distilled essential oils from the aerial parts of two collections of Sideritis congesta, an endemic plant of Turkey growing in Southern Anatolia, were analyzed by GC and GC/MS. Thirty-nine components were characterized in each oil representing 85–90% of the total components detected with β-pinene (34–35%) and α-pinene (24–25%) as major constituents.
