Abstract
In vitro antibacterial activity of ethanolic leaf extract of Rauwolfia tetraphylla was studied against selected pathogenic bacteria Bacillus cereus, Escherichia coli, Staphylococcus aureus and Yersinia enterocolitica by disc diffusion assay. Bioactive compound reserpine was isolated from the leaf. The results revealed that the ethanolic leaf extract and reserpine compound are potent in inhibiting these bacteria which cause gastroenteritis in human population. This work highlights that the inhibitory effect is on par with standard antibiotics.
