Volatile compounds from Achillea tenorii (Grande) growing in the Majella National Park (Italy).

This work presents the first reported phytochemical study on the hydro-distilled essential oil from Achillea tenorii (Grande), collected in the protected area of Majella National Park (Italy). The composition of the essential oil was very different from those reported for the other species of Achillea nobilis group, being constituted mainly by oxygenated monoterpenes, among which ketones, alcohols and acetates compounds were the most representative. The marker compounds of A. nobilis group were not detected while the most abundant phytoconstituents were α-thujone (29.7%), trans-sabinol (18.6%) and trans-sabinyl acetate (15.7%), revealing a composition quite similar to that of Artemisia absinthium. © 2014 © 2014 Taylor & Francis.
