In this study we assessed the chemical composition, antioxidant and antibacterial activities of Lavender essential oil. The antioxidant and antibacterial capacity of test sample was assayed by a linoleic acid system and conventional method of bacterial growth inhibition. The results demonstrated that the essential oil consisted of 1,5-Dimethyl-1-vinyl-4-hexenyl but yrate as the most abundant component (43.73%), followed by 1,3,7-Octatriene, 3,7-dimethyl- (25.10%), Eucalyptol (7.32%), and Camphor (3.79%). Lavender essential oil display the stronger antioxidant activity against lipid peroxidation in a linoleic acid model system and good antibacterial activity against four rhinitis-related bacteria including staphylococcus aureus,Micrococcus ascoformans, Proteus vulgaris and Escherichia coli.
Key words: Antibacterial, Lavender; antioxidant, essential oil, extraction, rhinitis.
