Abstract

Spathodea campanulata P. Beauv is extensively used in Indian traditional and folklore medicines to cure various human ailments. The preliminary phytochemical screening of the leaves revealed the presence of alkaloids, flavonoids, saponins, tannins, steroids and terpenoids. In vitro antibacterial studies of the leaf extracts were carried out on eight medically important bacterial strains using agar disc diffusion method. The antibacterial assay using petroleum ether leaf extracts showed good inhibitory activity against Klebsiella pneumoniae and compared with standard antibiotic Streptomycin.
