Abstract
This work aims to determine the antioxidant, antibacterial properties and chemical profile of the essential oil (EO) of Lavandula multifida (LM) at the flowering stage collected in northwestern Morocco. So far, information on essential oils of L. multifida remains limited. The extraction yield of the essential oil was 0.46%. The composition was determined by GC-MS-FID. Twenty compounds were identified and the major phytochemicals were carvacrol, ß-bisabolene, and careophyllene oxide (44.3%, 31.9%, and 5.8% respectively). In addition, information on the essential oil of L. multifida collected in the Rabat region is reported for the first time in this study. DPPH and FRAP tests were used to evaluate its antioxidant activity. Antibacterial activities were also studied. Indeed, the essential oil of L. multifida exhibited inhibition effects on the growth of various microorganisms, including S. aureus where the MIC and MBC were equal to 0.5 and 2μg/ml, respectively. Therefore, the use of Lavandula multifida essential oil shows great promise in various fields.
