Abstract

Seseli libanotis is an aromatic umbelliferous plant distributed sporadically on dry grassland egdes in Europe and Western Asia. The essential oil composition in the different plant parts was studied from plants collected on 9 sites in Austria and one site in Alto Adige, Italy. Monoterpenes as α-pinene, sabinene and β-myrcene and the sesquiterpene germacrene D were present in all essential oils from the aerial parts. Inflorescences and fruits had the highest essential oil contents. These essential oils from four sites were rich in acorenone B, while from other three sites they had carotol as a major component. Osthole as furocoumarin occurred in some oils. The root essential oils were dominated by α-pinene. The essential oil variability has been studied by principal component analysis (PCA) and discriminant analysis (DA) with plant parts or sampling site as a priori groups. PCA could well separate Inflorescence inflorescence and fruit essential oil samples from leaf and stem essential oil samples. DA differentiated well between the plant parts and most of the sampling sites.
