Chemical compositions of two different Thymus species essential oils

Thymus is one of the most important members of Lamiaceae family. Aerial parts of the plant have been widely used in medicine. It has been reported that most of these effects are related to phenolic compounds especially thymol and carvacrol in Thymus essential oil. In this study, aerial parts of Thymusdaenensis and Thymus lancifolius were collected from Kohgiluyeh and Boyer-Ahmad, Iran. Essential oils of aerial parts of these plants were gained by the hydrodistillation method and the chemical compositionswere analyzed by gas chromatography/ Mass spectrometry (GC/MS). The major components of the essentialoil of T. daenensis were thymol (39.91%), carvacrol (29.93%), linalool (5.55%), caryophyllene (3.5%) and geraniol (3.09%), whereas the major components of the essential oil of T. lancifolius were: carvacrol (25.55%), thymol (20.79%), linalool (16.8%), α-terpineol (6.34%), borneol (4.00%), caryophyllene (3.98%), p-cymene (3.38%) and cis-linalool oxide (3.21%). Linalool was reported as another major component in T. lancifolius.
