Analysis of volatile components of Lavandula luisieri L. by direct thermal desorption-gas chromatography-mass spectrometry
Volatile components of wild samples of Lavandula luisieri collected in Central and Southern Spain have been analyzed by direct thermal desorption coupled to gas chromatography-mass spectrometry (DTD-GC-MS). This method requires only 10-20mg of dry sample, allowing to obtain qualitative and quantitative results from different plant parts such as flowers and leaves. Average volatile yield calculated from 51 individual plants was higher for leaves (9.7mgg-1) than for flowers (2.9mgg-1). Samples presented a high variation in their yield and composition. Major components were camphor and 1,8-cineole (up to 80.9 and 76.7% in leaves; 87.8 and 85.2% in flowers, respectively); however, these compounds were not detected in several samples. Other major component (up to 60% in flowers and leaves) was 2,3,5,5-tetramethyl-4-methylene-2-cyclopenten-1-one. Multivariate analysis was applied to quantitative data from nine selected compounds in order to show the presence of several patterns in plant composition which were only partially related to the site of collection. © 2003 Elsevier B.V.
