ETUDE DE L’INFLUENCE DE LA COMPOSITION DE MELANGES D’EXTRAITS OBTENUS A PARTIR DE PLANTES NATURELLES LOCALES PAR CO2 SUPERCRITIQUE OU AUTRES, SUR DIFFERENTES ACTIVITES BIOLOGIQUES.

Abstract

Two medicinal plants, Capparis spinosa and Senna alexandrina, were used in this study to evaluate the influence of the combination of extracts on their antioxidant, enzymatic (anti-Alzheimer), and antifungal activities. The extraction methods employed include Soxhlet extraction with organic solvents (ethanol and hexane), static maceration extraction with methanol and acetone, and supercritical CO₂ extraction with ethanol as cosolvent. The main objective is to compare the efficiency of the extracts of these plants, individually and in mixture, by examining the extraction yields as a function of solvents and conditions, while considering the effects of polar and apolar solvents on the efficiency of the obtained extracts.
