We have carried out the extraction of the essential oils of the aerial part of the plant using the hydro-distillation technique which enabled us to reachan extraction efficiency of 0.585 %. The chemical composition of the essential oil was analyzed by GC/MS method therefore 35 components have been identified; the limonene (34.72 %), alpha-pinene (25.42 %), the β-pinene(8.59%), the α-Elemol (4.21 %) are the major components. The antibacterial activity of the essential oil has been measured

The antioxidant activity of the essential oil was evaluated using 2,2-diphenyl-1-picrylhydrazyl (DPPH) test which shows (IC 50 =58.6336 ± 0.7207)and the antioxidant power of reduction of iron (FRAP) shows (EC 50 =48.1936±0.5628)
