Abstract

The aim of this study is to evaluate the valorization of Cornulaca monacantha plant, a desert plant belonging to the Ramarame family, by extraction and estimation of biological activity, as it was harvested from Hamadin area - Al-Muqrin - Oued state in December 2023. The aerial part was extracted with the following solvents: distilled water, ethanol, a mixture of distilled water and ethanol (70/30), and we also detected some secondary metabolic compounds (alkaloids, flavonoids, terpenes, saponins), and some secondary metabolites. Through the extraction process, we found that the aqueous extract had the highest yield of 16.76%, and the results of quantification of phenols showed the highest value of ETOH/H2O extract estimated at 142.889mg EAG/g, while the highest value of flavonoids was for the aqueous extract 55.733mg EQU/g, and we performed the DPPH and FRAP test to study the antioxidant activity and found that the aqueous extract had the best antioxidant activity in both methods. Finally, the antibacterial activity was studied, where four strains of bacteria were tested at different concentrations and the results showed that some of the studied extracts have antibacterial activity .
