الملخص

Haloxylon scoparium Pomel is a medicinal plant belonging to the Amaranthaceae family; it is widely distributed in the Saharan atlas and locally called "Remeth". The aerial parts of this plant are traditionally used as anti-larvicides and treat eye and digestive tract problems. This work was done with the aim of identifying certain phytochemicals and evaluating the antioxidant activity of extracts prepared from the leaves and stems of the plant. The extracts are prepared using the maceration technique with two solvents of different polarities; the extraction yield is 12.95% for the aqueous extract and 51.5% for the methanolic extract, The highest rate of polyphenols is found in the methanolic extract (10.811±0.126μg gallic acid equivalent/mg of extract). The aqueous extract showed the highest contents of flavonoids (19.692±0.276 μg equivalent quercetin/mg of extract). The evaluation of the antiradical potency of the extracts against DPPH showed that the methanolic extract has the highest activity (IC50 = 44.33 mg/ml). The estimation of the antibacterial effect of the plant showed that the aqueous and methanolic extracts have no effects on Staphylococcus aureus strains; Escherichia coli and Pseudomonas aeruginosa. On the other hand, our results show that they do not preserve ground chicken meat.
