Abstract:Essential oils obtained by hydrodistillation from different organs (flowers, leaves, stems and roots) of Tunisian coriander (Coriandrum sativum L.) was analyzed. GC and GC-MS analysis enabled us to identify 64 compounds and revealed great qualitative and quantitative differences between the analyzed parts. In all organs, the main compound was (E)-2-dodecenal, followed by (E)-2-tridecenal, gamma-cadinene, (Z)-myroxide, neryl acetate and eugenol. Multivariate analysis (PCA) revealed a high similarity in the essential oils composition between upper leaves and flowers in one hand and basal leaves, roots and stems on the other hand. Further, it has been reported an organ-dependant distribution of essential oil compounds.
