ABSTRACT:
Chemical investigation on leaves oil of Hoslundia opposita, aromatic plant used
in traditional medicine, harvested from 20 localities of C?te d’Ivoire
was realized by GC and GC/MS. In total, 101 compounds were identified
accounting to 92% - 99%, aromatic compounds such benzyl benzoate and sesquiterpenes
namely germacrene D, β-caryophyllene and α-humulene hydroxyl were found as the major constituents. As regard,
the chemical profiles of our samples, it was found a great chemical variability
suggesting a high polymorphism degree. In order to study this chemical
variability, the results were submitted to the principal components and cluster
analysis which allowed distinguishing two main groups of essential oils with
respect to sampling site. The cluster I was dominated by benzyl benzoate (15%)
and thymol (7.4%) comprising 6 localities, cluster II was characterized by
phytol (8.5%) and α-humulene (7%) and constituted by 14 localities.
