The essential oil composition of Thymus tosevii and Thymus macedonicus from Bulgaria.
Essential oils composition of Thymus tosevii Velen. and Thymus macedonicus (Deg. et Ur.) Ronn. from Bulgaria were examined by analytical GC and GC-MS techniques. 39 components were separated in the oil of T. tosevii and 22 of them were identified, representing 94.37% of the oil. The most abundant constituents were: terpinyl acetate (43.59%), thymol (11.43%) and nerol (11.72%). More than 70 components were separated in the essential oil of T. macedonicus, 35 were identified, representing 96.03% of the oil. The major components were geranyl acetate (30.00%) and terpinyl acetate (17.30%), followed by lower amounts of nerol (14.25%), linalool (12.94%) and thymol (4.14%). Both examined taxa contained essential oils composed mainly from monoterpene oxygenate compounds while the fractions of monoterpene hydrocarbons as well as sesquiterpene components were very low.
