The volatile fraction of the whole plant and separated organs of Adenostyles briquetii Gamisans (syn. Cacalia briquetii ; family Asteraceae), an endemic species from Corsica, has been studied by headspace solid‐phase microextraction (HS‐SPME), GC and GC‐MS(EI and CI). A total of 141 components were identified, representing 93% of the entire amount. The volatile fraction was characterised by sesquiterpene hydrocarbons (52.8%) and oxygenated sesquiterpenes (25.9%). The major components were germacrene D (18.5%), zingiberene (12.9%) and β ‐oplopenone (10.8%). The influence of HS‐SPME parameters on the extraction of family components is reported for the first time. Copyright © 2007 John Wiley & Sons, Ltd.
