Abstract
The aim of this study is to determine the phytochemical analyses, antioxidant and antimicrobial activities of Reamuria vermiculata leaves extracts. Organic extracts (methanol, hexane, ethyl acetate, petroleum ether) were screened for their biochemical composition as well as antioxidant and antibacterial activities. In fact, Phytochemical screening of Reamuria vermiculata leaves showed the presence of flavonoids, coumarins, saponins, tannins, terpenes, and quinones. Biochemical screening showed that the methanol was the richest extract in phenolic and tanins with 179.68 mg GAE/ g and 56.25 mg CE/g, respectively. The analysis of DPPH radical scavenging activity and ABTS showed an important scavenging with ethyl acetate extract with IC50 of 0.0012mg/mL, and 0.0006mg/mL respectively. As well as, the methanol extract exhibited an antimicrobial property against bacterial strains. Listeria monocytogenes and Salmonella typhimurium were the most sensitive strains with minimum inhibitory concentration values of 0.3125 mg/mL. These results allow us to propose that Reamuria vermiculata is an excellent source for bioactive molecules exhibiting interesting biological capacities.
