Optimization of extraction of essential oil from local Lavender (lavandula angustifolia) and evaluation of the antioxidant and antifungal activities

Abstract

The optimization of the extraction of essential oil from Algerian lavender (lavandula angustifolia. L) by hydro distillation and the determination of the antioxidant and anntifungal activities were considered. A parametric study was carried out and based on the response surface methodology with particle size, water/solid ratio and extraction time, as factors. Results from the 2, 2’-azinobis-(3-ethylbenzothiazoline-6-sulfonate (ABTS) assay shows that the obtained extracts are some less effective antioxidants than butylated hydroxyanisole (BHA) and butylated hydroxytoluene (BHT) standards. The antifungal activity on solid medium by agar dilution method showed that the obtained essential oil revealed a good antifungal activity against (Fusarium oxysporium).
