(OVH) and Origanum onites L. (OO) were analyzed by GC/MS. Twelve compounds comprising 98.89% of the (OVH) essential oil were characterized, and the main components were thymol (58.35%) and ?-terpinene (23.22%). Twenty compounds representing 94.58% of the (OO) essential oil were identified, among which carvacrol (73.90%) and ?-terpinene (5.96%) were the major ones. Antiradical activities of essential oils investigated were tested using the DPPH radical-scavenging method. DPPH radical scavenging activities of two Origanum species essential oils were very high, and this was obviously related to their chemical compositions which were markedly rich in phenolic components such as thymol and carvacrol.eninfo:eu-repo/semantics/closedAccessCarvacrolDPPHEssential OilGC/MSOriganum Onites L.Origanum Vulgare L.
