ABSTRACT
Turnera ulmifolia Linn. belonging to family Turneraceae was investigated to evaluate in-vitro antibacterial activity of ethanol extract of the leaves against gram negative bacteria such as Salmonella typhi, Pseudomonas fluorescens, Pseudomonas aeruginosa and Escherichia coli. The pathogens were tested by disc diffusion assay method and minimum inhibitory concentration was evaluated. An attempt has been made to compare the activity of extract with standard ciprofloxin. The pathogens were used in the study was showed potential activity of the ethanolic extract of the plant. Maximum activity was seen in case of Pseudomonas fluorescens where the zone diameter was 32 mm (300μg/ml).
