| Abstract | ||
| Several researches have been focused on aromatic plants extracted essential oils, indicating that they have many biological properties. In this context, we tried to evaluate the in vitro antibacterial and antioxidant activities of the Lavandula officinalis dried flowers essential oil. The extraction was carried out by hydrodistillation of the plant flowers, the yield was close to 1.45 %.The essential oil composition study by GC/MS ,identified 28 terpenes essentially composed by the acetate (17.85% , 89.980 min); 1.8-cineole (9.97 % ,53.512 min); γ-terpineol (10.23, % 52.425 min) and camphor (12.98 % ,24.410 min). The well and disk methods demonstrated a strong antibacterial activity of the Lavandula officinalis flowers essential oil. Staphylococcus aureus ATCC 9027, Escherichia coli ATCC 25922 and Enterobacter aerugenes ATCC 1710 were the most sensitive bacteria, with inhibition zone diameters speared from 30 to 40 mm. Also, this essential oil exhibited a slight antioxidant activity carried out by the DPPH and FRAP methods. | ||
