Abstract: Over 30-55 compounds were identified in the essential oils from five different collections of Origanum vulgare L. (Family-Lamiaceae) by the combination of GC and GC/MS analysis. Linalool (34.4%), thymol methyl ether (45.2%) and thymol (41.4%-68.5%) were identified as major constituents in different collections. No other monoterpene hydrocarbon was present in collections from site III except α-pinene (0.2%). 1,8-cineol, E-β-ocimene, trans-sabinene hydrates, cis, p-menth-2-en-1-ol, carvacrol methyl ether, α-muurolene, cubebol, selina-11-en-4- α-ol, spathulenol, epi-α–bisabolol and epi-α-cadinol though in minor amount were identified only in collections from site V. All the oils exhibited good to moderate in vitro antioxidant activity when tested for reducing power activity, 2, 2,-diphenyl-1-picrylhydrazyl (DPPH) radical scavenging activity and chelating activity of Fe2+ ions.
