Reputed to be a plant rich in antioxidants, Abelmoschus esculentus or okra is a very effective vegetable against diabetes. In this work, we made a qualitative study of the bioactive compounds contained in the leaves and seeds of okra, through a phytochemical screening. Subsequently, the antioxidant and antimicrobial activities of these extracts were studied. The Folin-Ciocalteu reagent was used to evaluate the content of the phenolic compound. The DPPH● radical made it possible to measure the antioxidant power of the extracts. The phytochemical analysis made it possible to high the presence of substances with great therapeutic values ​​(polyphenols, flavonoids, tannins, alkaloids, etc.). The antibacterial activity was measured on bacterial strains. The antioxidant capacities reveal that the extracts of the leaves and seeds of okra possess an interesting anti-free radical activity with IC50 values ​​of 06 ± 0.21 mg / mL and 8.85 ± 0.28 mg / mL respectively for the leaves and the seeds. . Biological analysis shows that the E. faecalis strain is resistant to different extracts. E. coli, S. aureus, and P. aeruginosa strains show some sensitivity to ethanolic extracts. However, E. colis and S. aureus strains show the best antimicrobial activities with a MIC of 3.75 mg/mL for crude ethanol extract and ethanol fraction of leaves and seeds.
