Backgound: Lavandula species are one of the most popular aromatic plants and are well-known as herbal medicines with a number of useful biological properties. Objective: To investigate the chemical composition, antioxidant and antibacterial activity of essential oil of lavandula dentate a number of tests were carried out. Methods: The essential oil, was obtained by hydrodistillation, with a 1.4±0.01 (w/w) yield, then the chemical composition was analyzed by gas chromatography coupled with mass spectrometry (GC-MS). The antimicrobial activity of the essential oil evaluated against sex microorganisms (E. Coli, Listeria, S. Aureus, B. Ceraus, P. Aeruginosa and Salmonella Enteritidis) using paper disc diffusion method. The anti-free radical activity was assayed using DPPH• and ABTS•+ methods and phosphomolybdenum methods. Results: The results of the GC-MS showed the presence of 31 components, The main components are Carvacrol (44.38%), beta-Bisabolene (24.82%), Caryophylleneoxide (3.36%), Camphene (2.92%) and Spathulenol (2.44%). The essential oil inhibited the growth of all tested bacteria except for P. Aeruginosa, and the minimum inhibitory concentration was determined to be around 4.6-92µg/mL. The level of antioxidant activity estimated by DPPH was (IC50 = 70±1.03µl/ml) and ABTS was (0.032±0.0006 Equi mg trolox/ml DW) and Phosphomolybdenum was (4.66±0.007 Equi TROLOX mg/ml). Conclusion: The results of this study showed that essential oil of lavandula dentate present an interesting antioxidants and antimicrobial activity, which could be used as a potential source of natural antioxidants and bioactive molecules and could present a very promising alternative in the field of antimicrobial applications.
Keywords: lavandula dentata, Essential oil, Chemical Composition, Antioxidant activity, Antimicrobial activity.
