ABSTRACT
There are many plants which were the subject of recent research in the fields pharmaceutical, cosmetic and agroalimentary because of their chemical composition and their several therapeutic activities. Among these plants, the species of Rosmarinus officinalis (rosemary) and Populus alba (white poplar).The present study aims to examine the yield and quality of essential oil of rosemary and white poplar. Then, we have to determine the chemical composition of the essential oils isolated from these plants. The chemical composition was determined by hydro‐distillation, analyzed by Gas Chromatography/Mass Spectrometry. The results of physicochemical analysis reveal that the essential oils of the both plants are of good quality. The Gas Chromatography/Mass Spectrometry analysis reveals that the major
components determined in Rosmarinus officinalis essential oil were Camphor (22.35%), Verbenone (23.48%), Borneol (16.63%), and Eucalyptol (11.73%) while the major components determined in Populus alba essential oil were 1, 8-Cineole (38.02%), β-Eudesmol (20.58%), δ-Cadinene (8.30%), α-Eudesmol (6.75%).
Keywords: Rosmarinus officinalis, Populus alba, Essential oils, GC/MS.
