The main constituents of the essential oils were characterized by GC-MS which resultedin the identification of 26 components, representing 100 % of the oil. The dominant compounds in the oil offruits were trans-caryophyllene (19.17 %), sabinene (18.05 %) and 1,8-cineole (16.13 %), ?-terpinyl acetate(6.91 %) and dihydroselarene (6.73 %). Antimicrobial activity was tested using the disc diffusion method.According to the inhibition zones, the essential oils were active against all of the tested microorganisms. Theessential oils showed the susceptible inhibition zones, but they were less effective against bacterial strainscompared to ampicillin and ofloxacin. The organisms most susceptible to these essential oils were Enterococcusfaecalis ATCC 29212. However, further studies must be performed to confirm the safety of these oils for use asan antimicrobial agent.eninfo:eu-repo/semantics/openAccessAntimicrobial activity, GC-MS, essential oils, Vitex agnus castus L.ArticleQ22-s2.0-84928267027
