Abstract
Samanea saman is a tropically distributed medicinal plant. Antimicrobial activity of aqueous extract of this plant was investigated by Well-diffusion method against three organisms: Escherichia coli, Staphylococcus aureus and Candida albicans. The plant extract showed inhibitory activity against all the tested organisms. Five mg/ml inhibited the growth of E. coli but slightly higher concentration of 10 mg/mL was necessary to show inhibition against S. aureus and C. albicans. Phytochemical screening of the plant revealed the presence of tannins, flavonoides, saponins, steroids, cardiac glycosides and terpenoids. The study scientifically validates the use of plant in traditional medicine.
Key words: Samanea saman, Escherichia coli, Staphylococcus aureus, saponins, tannins, alkaloids, glycosides and flavonoides.
