This research will look at the plants Haloxylon articulatum Bioss and Arnebia decumbens Vent Coss and Kral, which grow in OuedSouf, Algeria. Which treatments are often employed in medical science. This research focuses on the antioxidant impact and biological activity of plants, taking into consideration the extraction of the active ingredient's phenol. Using a scanning equipment and high-performance liquid chromatography, the active components were discovered (HPLC). The present research used a qualitative and quantitative method to get a deeper understanding of the body of information around the extraction process. Both the antibacterial activity of the phenolic extracts and their oxidation levels were investigated separately. The findings demonstrated that there was a significant impact on the production of free radicals as well as the multiplication of a number of different bacterial strains. In addition, the antibacterial agents known as "polymyxin B" and "ampicillin" were shown to have less of an effect on the bacteria Bacillus cereus ATCC 14579 and E. coli ATCC 25922 than the phenolic extracts did.
