For this, gas chromatography coupled with mass spectrometry was used. Carvacrol with 62.41% was identified as the main component, followed by β-caryophyllene 8.84%, α-bergamoten 6.75%, p-cymene 6.24%, geraniol 4.29%; and α-humulene, β-felandrene, 1-octen-3-ol, caryophyllene oxide, 4-terpineol, E-citral, γ-terpinene, z-citral in small amounts. Carvacrol gives oregano multiple antioxidant, microbiological and food preservative properties, as well as potential applications in perfumery and cosmetics.</p> <p><strong>Keywords:</strong> Oregano, essential oil, gas chromatography, mass spectrometry.</p> <p>References</p> <p>[1]J.
