	abstract = {The composition of the essential oil hydrodistilled from the aerial parts of Thymus vulgaris L. grown in Jordan has been determined by GC and GC-MS. Variations in oil composition and yield between cultivated and wild-growing plants collected from different localities, at different altitudes, have been also evaluated. Higher oil yields were observed in plants growing wild (3.7-5.6\% of dried material) than in cultivated plants (1.1-2.0\%), and those collected from the Mshaqar region, in the middle of Jordan and at the highest altitude, were the richest in oil (similar to 5.4\%). Generally, the oil was characterized by marked levels of phenolic monoterpenoids (mainly thymol and carvacrol) in the range 70.8-89.0\%. High levels of the monoterpenoid hydrocarbons p-cymene (3.4-8.2\%) and gamma-terpinene (1.6-7.7\%) were also observed. Other major components were 1,8-cineole (up to 2.1\%), alpha-thujone (up to 1.2\%), camphor (up to 1.1\%) and fl-caryophyllene (0.2-2.8\%). With the exception of plants growing wild in the Ramtha region, in the far north of Jordan, carvacrol was found as the principal phenol of all other oils (50.6-86.1\%) and was dominant (>85\%) in wild plant oils. The oil from Ramtha was characterized by the highest level of thymol (similar to 63.8\%) as the dominant phenol and was most abundant in p-eymene (8.2\%), 1,8-cineole (2.1\%) and gamma-terpinene (7.7\%). In addition to assigning carvacrol or thymol chemotypes to the plant, the high content of active monoterpenoid phenols strongly suggests a potential use of Jordanian thyme oil in cough products and antimicrobial-herbal drug combinations.
