Physico-Chemical Profile and Antioxidant Activities of Eucalyptus globulus Labill and Eucalyptus citriodora Essential Oils in Ethiopia

Bekri Melka Abdo*

Eucalyptus is expressed as huge potentials for Ethiopian climatic conditions. Looks for quality of essential oils was an aim for this study. Hydro distillations of fresh leaves were yielded 1.75% (E. globulus) and 2.00% (E. citriodora) essential oils. Major compounds with 1, 8-Cineole (77.24%) and α-Pinene (10.54%) were indentified from E. globules essential oil. Eucalyptus citriodora essential oil was abundant with Citronellal (73.86%) and Citronellol (14.13%). The results of DPPH assay indicated that weak free radical scavenging activities with IC₅₀ value of 795.42 mg/mL for E. globulus, 169.64 mg/mL for E. citriodora and 0.577 mg/mL for the reference Ascorbic acid. The overall quality of E. globules and E. citriodora essential oils are comply the international specifications.
