Antimicrobial activity of Elaeocarpus sphaericus

Antibacterial activity of petroleum ether (PE), benzene (BE), chloroform (CE), acetone (AE) and ethanol (EE) extracts of dried Elaeocarpus sphaericus fruit was investigated against 28 gram-positive and gram-negative bacteria using the disc diffusion and plate dilution methods. The AE fraction showed marked antimicrobial activity against ten organisms. BE was active against Salmonella typhimurium and Morganella morganii, and EE against Plesiomonas shigelloides, Shigella flexnerii and Sh. sonneii. The alkaloids and flavonoids present in the plant appear to be of chemotherapeutic interest.
