Abstract
This study is the first to investigate the chemical composition of essential oil (EO), secondary metabolites as well as its biological activities of eucalyptus marginata L. and eucalyptus pauciflora L. leaves extracts. EOs have been analyzed using GC-MS apparatus. The chemical profile of the EOs of eucalyptus marginata L. and eucalyptus pauciflora L. mainly included 1,8-cineole (27.47 %) for the first specie while globulol (54.86 %) and -Gurjunene (24.11 %) for the second one. Antioxidant and antimicrobial activities were also studied. The EOs of E. marginata and E. pauciflora exerted notable antibacterial activities especially against Staphylococcus aureus, and antifungal activity against Candida parapsilosis. The obtained EOs have a significant antioxidant potential. The biological activities and potentialities of EOs recommend their use in the formulation of natural and environmentally friendly pharmaceuticals.
