Abstract

Leaf extracts of Citrus aurantifolia, was investigated for antibacterial activity against Salmonella typhi, Salmonella Paratyphi A and Salmonella Paratyphi B using agar-well diffusion and gradient serial dilution methods. Phytochemical screening was conducted in order to detect secondary metabolites. The in vitro antibacterial activity of the extracts showed antibacterial activity againsttyphi and S. Paratyphi B. Watersoluble leaf extracts demonstrates higher zone of inhibition (19mm) against S. Paratyphi A.S. Typhi was found resistant to both water and chloroform soluble leaf extracts but sensitive to ethanolic leaf extracts at 50µm/mlconcentration. Both S. Paratyphi A and S. Paratyphi B were found resistant to ethanolic leaf extract. The occurrence of alkaloids, flavonoids, tannins, saponins, steroids, terpenoids and phenols in the aqueous leaf extracts of C. aurantifolia justifies its use in the folklore medicine.
