Abstract
Essential oils have important biological activities. Which leads to the study of the biological activity of these essential oils. The aim of this work is to study the antibacterial, antifungal and antioxidant capacities of extracts of cumin and fennel, and to compare the two compounds. The extraction was carried out by hydrodistillation of the clevenger type, gave a yield (1.11% for cumin and 0.55% for fennel). The results of the physicochemical analyzes of the essential oil comply with the standards (AFNOR), the experimental work is devoted to achieving :
The extraction of essential oils from two plant species and the physico-chemical analysis of the essential oils extracted.
The study of the antibacterial power of essential oils and their synergistic effect against bacterial strains (Gram (+) / Gram (-) and the determination of the minimum inhibition concentration (MIC).
The study of the antifungal power of essential oils against a fungal strain and the determination of the minimum inhibition concentration (MIC) after dilutions of essential oils.
The study of the antioxidant power of essential oils by the method of DPPH (2,2-diphenyl-1-picrylhydrazil).
