The oils obtained through steam distillation of the dried leaves from each cultivar varied from 1.38% to 2.04%, depending on the cultivarused. The highest oil content was obtained from cv “Madrid” followed by “RH-1” and “Laval-1.” More than 95% of the oil, with a total of approximately 22 components were identified in the samples. Oxygenated monoterpenes were the main group of constituents in all cultivars. Cultivar “Laval-1,” recentiy developed in Quebec, “Madrid” from Spain and “RH-1” from Germany were established to belong to thymol-chemotypes. Cultivar “QDLB” characterized by its content of thymol (approximately 39%), carvacrol (17%) and linalool (3.5%) in the oil, was also found to belong to “thymol”-chemotypes, while “RH-2” with carvacrol (40%) was found to be a carvacrol-chemotype.
