Twenty-four steam-distilled samples of essential oils from inflorescences from Origanum vulgaressp. hirtum (Link) Ietswaart growing wild in Calabria, southern Italy, were analyzed by gaschromatography and gas chromatography/mass spectrometry. A total of 56 compounds wereidentified. The main components of the essential oil were thymol and carvacrol, while their biogeneticprecursors, p-cymene and 
-terpinene, were the most aboundant monoterpenes. The relativeamounts of the two main constituents were comparable to the literature data on this species. Fourchemotypes were identified in Calabria on the basis of the phenolic content, i.e., thymol, carvacrol,thymol/carvacrol, and carvacrol/thymol chemotypes. The first chemotype was the most frequent.A significant variability of composition possibly correlated with the individual genotypes wasobserved.Keywords: Oregano; Origanum vulgare ssp. hirtum; essential oil composition; GC/MS
