Abstract
The essential oil obtained by hydrodistillation from the inflorescences of Tanacetum macrophyllum (Waldst. & Kit.) Schultz Bip. originating from Bulgaria was analysed by GC-MS. Thirty-nine components were characterized, representing 84.4% of the total oil components detected. The extracted essential oil was found to be enriched in oxygenated monoterpenes (65.5%). The main constituents were identified as 1,8-cineole (23.7%), camphor (22.8%), borneol (5.9%), bornyl acetate (4.4%) and camphene (3.8%). This is the first report describing the chemical composition of a Tanacetum macrophyllum essential oil of Bulgarian origin.
