Infraspecific chemical variability of the essential oil of Lavandula dentata L. from Algeria

Fifty‐five samples of essential oil obtained from individual plants of Lavandula dentata L. var. dentata from Algeria were analysed using GC and 13C‐NMR spectroscopy. The results were submitted to chemometric analysis (k‐means clustering and principal component analysis). Two principal clusters of e...

Description
Summary:Fifty‐five samples of essential oil obtained from individual plants of Lavandula dentata L. var. dentata from Algeria were analysed using GC and 13C‐NMR spectroscopy. The results were submitted to chemometric analysis (k‐means clustering and principal component analysis). Two principal clusters of equal importance were distinguished within the essential oil of the individuals of L. dentata. The samples belonging to cluster I were characterized by a very high content of 1,8‐cineole (mean value 48%). Conversely, the mean composition of the samples of cluster II were dominated by 1,8‐cineole, β‐pinene, trans‐pinocarveol and linalool. Copyright © 2005 John Wiley & Sons, Ltd.
