Essential oils from aerial parts of Thymus vulgaris have been obtained by hydrodistillation. Their components have been identified by gas chromatography/mass spectrometry. Samples were collected in Catalonia (northeastern Iberian peninsula), specifically in four locations along the Llobregat river basin. Such locations have different altitudes with respect to sea level (1500 m; 700 m; 300 m; 100 m), and have differences in pluvial regime and mean temperature. At 700 m, samples were collected from a transplanted specimen from 1500 m, in order to check the influence of the change in environmental conditions. Two different chemotypes have been characterized. Samples collected at 300 m have a dominant chemotype 1,8‐cineole, with 20% (approx.) essential oil content. The other samples have linalool as dominant chemotype with a 40–70% content, according to vegetative stage. Copyright © 2007 Society of Chemical Industry
