• Artemisia umbelliformis Lam.
• genepi liqueur
• food safety

Artemisia umbelliformis, commonly known as "white genepi", is characterized by a volatile fraction rich in alpha- and,beta-thujones, two monoterpenoids; under European Union (EU) regulations these are limited to 35 mg/L in Artemisia-based beverages because of their recognized activity on the human central nervous system. This study reports the results, of an investigation to define the geographical origin and thujone content of individual plants. of A. umbelliformis from different geographical sites, cultivated experimentally at a single site, and to predict the thujone content in the resulting liqueurs through their volatile fraction. Headspace solid phase microextraction (HS-SPME) combined with gas chromatography mass spectrometry (GC-MS) and non-sepatative HS-SPME-MS were used as analytical platforms to create a database suitable for chemometric description and prediction through linear discriminant analysis (LDA). HS-SPME-MS was applied to shorten analysis time. With both approaches, a diagnostic prediction of plant geographical origin and (ii) thujone content of plant related liqueurs could be made.
