Lamiaceae family members are important in pharmacology and perfumery industry because they contain volatile and aromatic oil. Origanum onites L. and Thymbra spicata var. spicata L. are the most widely used and most exported species. The volatile components of the leaves and flowers of Origanum onites L. and Thymbra spicata var. spicata taxa were determined by Headspace Solid Phase Microextraction (HS-SPME) technique combined with gas chromatography/mass spectrometry (GC / MS). 33 different components of Origanum onites were identified and the main components were p-cymene (11.45%), γ-terpinene (11.89%), linalool (14.35%), thymol (20.03%) and carvacrol (26.91%), respectively. For Thymbra spicata var. spicata L., 36 different compounds were identified and the main components were p-cymene (11.72%), γ-terpinene (10.96%), linalool (13.44%), thymol (18.92%) and carvacrol (27.34%), respectively. Oxygen containing monoterpenes have been found to be high.
