The essential oils obtained by hydrodistillation of four Labiatae herbs, namelySalvia crytantha. Montbr. et Auch.,Satureja cuneifoliaTen.,Thymbra spicata L. andThymus cilicicusBoiss. et Bal. growing wild in Middle Anatolian provinces of Turkey, were analyzed by GC and GC/MS. Fifty-four compounds were identified inS. cryptanthaoil of which camphor (18.1%), 1,8-cineole (17.8%), and bornyl acetate (11.4%) were major. In the oils ofS. cuneifolia, 38 compounds were identified, with thymol (43.6–65.5%), carvacrol (4.7–31.2%), γ-terpinene (trace-13.7%) and p-cymene (trace-11.5%) being dominant. Of the 33 compounds identified inT. spicataoil, the main components were p-cymene (22.1%), γ-terpinene (21.4%), carvacrol (21.1%) and thymol (11.8%). The oil ofT. cilicicus, which contained 35 constituents, was found to be rich in α-terpineol (16.4%) and camphor (9.7%).
