PHYTOCHEMICAL SCREENING AND ANTI-BACTERIAL ACTIVITY OF METHANOLIC EXTRACTS OF THE AERIAL PARTS OF Atriplex halimus L., FROM BISKRA (ALGERIA)
The objectives assigned to the present study are the phytochemical screening of several secondary metabolites and the evaluation of the antibacterial activity of the methanolic extracts of the aerial parts of Atriplex halimus L. Phytochemical screening revealed the presence of substances with high therapeutic values (flavonoids, tannins, polyphenols, coumarin, etc.). The antibacterial activity of the extracts is carried out by the diffusion method on agar medium vis-à-vis sixteen bacterial strains, chosen according to the traditional use of this species in Algeria: Staphylococcus MRSA, Staphylococcus aureus, Staphylococcus ATCC 00, Streptococcus Sp, Enterococci Sp, Enterococci feacalis ATCC 12, Salmonella, E. coli ESBL +, Klebsiella pn Marseille, KpC+, Kp ETP R / IMP R, Serratia Sp, Serratia environmental, Pseudomonas aerogenosa ATCC 53, Pseudomonas VIM 2, Bacillus. The study shows a remarkable antibacterial activity against Gram+ bacteria compared to Gram- bacteria.
