Abstract
AbstractThe composition of the essential oil of twigs of individual trees of Abies alba Miller from Corsica was investigated by CC, GC (RI), GC–MS and 13C‐NMR. Among the 65 identified compounds, limonene, β‐phellandrene, α‐pinene, camphene and β‐pinene were found to be the major components. Fifty‐three oil samples were analysed and the results were submitted to chemometric analysis (K‐means clustering and principal component analysis). Two groups were distinguished within the essential oils. Samples belonging to the first group (64% of the samples) were characterized by a very high content of limonene (mean value 46.1%). Conversely, the mean composition of the samples of the second group (36% of the samples) was dominated by camphene, α‐pinene and limonene. Such a chemical composition is reported for the first time within A. alba essential oils. Copyright © 2007 John Wiley & Sons, Ltd.
