title: Essential oil composition of Achillea clusiana from Bulgaria.
abstract: The essential oil compositon of Achillea clusiana Tausch from Bulgaria has been studied by GC and GC/MS. Fifty-four components were registered, representing 92.5% of the oil. The oil was characterized by the presence of oxygenated mono- and sesquiterpenoids. The main components were beta-thujone (17.2%), 1,8-cineole (11.2%), camphor (11.1%) and alpha-thujone (7.8%). Farnesol (3.1%), nerolidol (2.7%) and oxygenated nerolidol derivatives (cabreuva oxides A-D, isohumbertiols A-D, bejarol and 7-hydroxy-6,7-dihydro-5,6E-dehydronerolidol) were the main sesquiterpenoids in the oil.
