- Abstract
This study aims at evaluating the antioxidant activity and antifungal essential oil of lavender. The extraction of essential oil of Lavandula officinalis was performed by steam distillation. The yield of HE increases with time before stabilizing. This yield is about 1.36 ± 0.2%. The analysis of the essential oil of Lavandula officinalis by CGC process has identified 49 compounds. Linalyl acetate (15.26%), Linalool (10.68%), 1,8 - cineole (10.25%), γ?-terpinene (11.2%) and camphor (11.25%) were the main components. The study of antioxidant capacity by the DPPH • method showed the existence of an antioxidant activity of essential oil of dried Lavandula officinalis flowers. Purification and microscopic study of isolated strains permit to identify five types of molds including: Aspergillus, Penicillium, Mucor, Rhizopus and Alternaria. The study of the contamination shows a dominance of Aspergillus and Penicillium. Assessing the antifungal activity revealed inhibition of mold growth for most strains tested.
