title: Analysis of volatile constituents isolated by hydrodistillation and headspace solid-phase microextraction from Adenostyles briquetii Gamisans.
abstract: 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 beta-oplopenone (10.8%). The influence of HS-SPME parameters on the extraction of family components is reported for the first time.
