| Résumé : | Essential oils obtained by hydrodistillation of leaves (LV), flowers (FL) and fruits (FR) of Hypericum hircinum subsp. majus from Marche (Italy), were analyzed by gas chromatography-flame ionization detector (GC-FID) and gas chromatography/mass spectrometry (GC/MS). Ninety-two volatile components were identified in the oils, representing 81.41–94.36% of the total oils. The major compounds were cis-β-guaiene (23.25–41.23%) and δ-selinene (8.48–25.20%) in LV, δ-selinene (18.29%) and limonene (15.23%) in FL, limonene (14.01–38.72%) and β-pinene (9.88–16.31%) in FR. The oils from LV and FL were dominated by sesquiterpene hydrocarbons, whilst the FR oils were rich in monoterpenes. Seasonal changes in relative percentages of representative groups and compounds of the oils were discussed. |
