Abstract:

The aim of this study was to investigate and compare the chemical composition of essential oils obtained by Clevenger-type apparatus from capitula (TCC) and aerial parts including leaves and stems (TCA) of Tanacetum cilicicum (Boiss.) Grierson from Turkey. TCC and TCA essential oils were separately analysed by GC-FID and GC/MS. Forty and thirty-two compounds were identified, representing 99% and 94.4% of the oils of TCC and TCA essential oils, respectively. The main constituents of the oil of the TCC were camphor (28.8%), (E)-nerolidol (16.9%), trans-chrysanthenyl acetate (12.8%) and 1,8-cineole (8.9%), whereas the oil from TCA comprised mainly trans-chrysanthenyl acetate (22.2%), borneol (19.4%), camphor (11.2%), 1,8-cineole (10.2%) and (E)- nerolidol (9.2%). The results showed that TCC and TCA essential oils were rich in oxygenated monoterpenes and oxygenated sesquiterpenes. This study is the first to study the essential oil composition of different parts of Tanacetum cilicicum separately. Also, to the our best of our knowledge, (E)-nerolidol was found in the Tanacetum species as the major compound for the first time.
