RESUMO
Anabasis articulata is a Saharan plant used by Algerian traditional medicine practitioners for medicinalpurposes. The objective of this study was to investigate the antioxidant properties of the extract and fractions ofthe leaves of A. articulata. The phenolic compounds were also quantified in this plant. Anabasis articulata wasexamined for antibacterial activities of its methanolic extract using disc diffusion method. The bacteria testedinclude Pseudomonas aeruginosa ATCC 14028, Salmonella typhimurium ATCC 9027 and Bacillus subtilisspizizenii ATCC 6633. The results showed that methanolic extract exhibits a higher level of phenolic compounds(230.000±0,415) as compared to all other extracts. The FRAP test revealed that the methanolic extract has ahigher reducing power (0.1 mg / ml) compared to other extracts. IC50 (DPPH) was ranged from 3.200±0.088 to4.900 ± 0.130. The compounds quantified by HPLC in the crude extract and fractions were quercetin andascorbic acid. The results obtained indicated that A. articulata exhibits a good potential to prevent diseases andit might also be used as a natural preservative for food or cosmetic products.
