Abstract The present study comprises screening some phytochemical compounds, antimicrobial activity and antioxidant activity in methanolic and aqueous extracts of Tribulus terrestris L fruits. The phytochemical analysis revealed the presence of alkaloids, Tannins, Glycosides, Flavonoids, Saponins, and Phenols. A well-diffusion method determined the antibacterial effect of T. terrestris extracts against both Gram-positive (Staphylococcus auras and Methicillin-resistant Staphylococcus aureus ATCC43300 (MRSA), and Gram-negative bacteria Pseudomonas aeruginosa, Proteus mirabilis, Klebsiella pneumoniae, and Escherichia coli ATCC25922. The methanolic extract was the most active extract against tested bacteria with a minimal inhibitory concentration (MIC) value of 6.25mg/ml. An antioxidant activity using DPPH assay showed that IC50 of methanolic and aqueous extracts were 3.94μg/ml and 22.45μg/ml, respectively).
