dc.description.abstractThe direction of agriculture in Algeria encourages the development of dry areas and the development of crops adapted to global warming. Prickly pear cactus is a dry climate-adapted plant that remains unexplored in Algeria. Prickly pear cladodes and the seeds contain bioactive components that are beneficial to health. The juice obtained from the cladodes and the seed oil of the Opuntia ficus indca are the subject of this work. The leaves were harvested in 2021 in the Daira d'Aïn El Hadjel region, west of M'sila, Algeria, to evaluate the physicochemical composition, TPC, flavonoid content, antioxidant activity and antibacterial activity. The yield of cladodes juice was about 79.02%. Physicochemical and TPC analysis showed that cladodes juice was rich in polyphenols (4.6 g/100 g) and flavonoids (38.35 mg/100 g), and the anti-radical activity was determined by DPPH test. Leafy sap from spiny species gave us high marks for antioxidant activity, and has got an effect on some of bactirial strains like: Staphylococtus aurous, E coli, Salmonella typhimirum, Serratia marcesscens. Results of these analyzes showed that cladode juice is rich in nutrients and has a potential antioxidant activity. The prickly pear seeds are harvested in summer 2021 in the western region (Ain Defla), and the seed oil yield is weak (5%), so a large seed volume of around 30-35 kg is required to have only 1 liter of oil. we did The antibacterial activities and results were as follows: Escherichia coli, Pseudomonas, Salmonella, and Klebsiella pneumoniae strains were relatively resistant to Soxhlet oil, and Escherichia coli and S. marcescens strains were relatively resistant to cold-pressed oil. Resistance is the same. The 3 samples, cold pressed oil, 90° pressed oil and 160° pressed oil, were the most proven oils to be effective against Escherichia coli, Pseudomonas, Salmonella and Klebsiella pneumoniae; between 11 and 19 mm inhibition zone diameter.en_US
