At the end of this study which was carried out at the Laboratory of Biotechnology, Pharmacology, Microbiology and Environment of the Ain Chock Faculty of Sciences of Casablanca, with the aim of evaluating the antimicrobial activity of an exotic fruit introduced in Morocco F. sellowiana. Three organic extracts of the fruit and sheets were prepared; Hexanic, acetonic and aqueous extracts. The results obtained made it possible to conclude that the aqueous extracts give the best extraction yields, followed by the acetonic and hexane extracts with a richness of the sheets in extractable compounds with respect to the fruit. The aromatogram test showed an inhibitory power of the aqueous extracts of the sheets more pronounced than that of the fruit in comparison with the acetonic and hexane extracts towards the strains studied: E. coli, P. aeruginosa, B. cereus, S. aureus et C. albicans. This bioactivity can be attributed to flavonoids, terpenoids, coumarins, saponins, steroids and tannins identified as major compounds in phytochemical screening. As it was noticed from the MIC results that gram-positive bacteria were more sensitive than gram-negative strains.
