Sesbania grandiflora Linn belonging to family Fabaceae is a well-recognized medicinal plant in numerous countries like India, Srilanka and Southeast Asia. The present study examines the phytochemical screening of leaves of Sesbania grandiflora. Preliminary phytochemical analysis revealed the presence of nine compounds such as alkaloids, flavonoids, phenol, quinones, saponins, steroids, proteins, tannins and terpenoids. A comparative antimicrobial activity of dried leaf extract was evaluated against four pathogenic strains names Escherichia coli, Pseudomonas aeruginosa, Staphylococcus aureus and Klebsiella pneumoniae. The phytochemical analysis revealed the presence of alkaloids, flavonoids, saponins, phenols, tannins, terpenoids, quinones, steroids and proteins. Twenty compounds were observed in extract of petroleum ether and about thirty compounds were observed in extract of ethyl acetate by GC-MS. The result suggest that leaves are a rich source of valuable primary and secondary metabolites exhibiting the antimicrobial activity.
