Abstract	The plant of oregano is amongst the most important spices, widely used worldwide. One of the most significant commercial species is the Origanum vulgare ssp. hirtum that is cultivated in the Mediterranean region. This type of crop is well adjusted to dry conditions, also on limestone ground. The goal of this project was the qualitative and quantitative analysis of the components of the essential oil of oregano. The analysis was conducted on specimens of different genotype. Collection of the essential oil was carried out through steam distillation with a Clevenger apparatus. Subsequently the analysis of the essential oils was performed viagas chromatography coupled to mass spectrometer (GC/MS). The 33 specimens analyzed were divided in to 3 different groups (type A, type B and C). The results revealed that the main components of the essential oil were phenolic compounds such as thymol and carvacrol and also their precursors, γ-terpinene and p-cymene. The 3 different types of specimens, showed fluctuations in their percentages. This outcome suggests that their qualitative and quantitative composition is affected by the genotype, the type of cultivation and the environment of the plant.
