Achillea wilhelmsii and Achillea lycaonica collected from different localities in Turkey, were subjected to hydrodistillation to yield essential oils which were subsequently analyzed by GC and GC/MS. The main constituents of the oils were identified and antimicrobial bioassays were applied. Camphor (39.62 %) was the main component in the oil of Achillea wilhelmsii. The oil of Achillea lycaonica contained L-camphor (43.19 %) as main constituent. All tested microorganisms were inhibited by the essential oils. On the other hand both essential oils showed strong antifungal activity against Alternaria brassicola than other tested microfungi.eninfo:eu-repo/semantics/closedAccessAchillea lycaonicaAchillea wilhelmsiiAntimicrobial activityChemical compositionEssential oilArticle202123812442-s2.0-53949113141Q4
