Abstract: The present study was undertaken to explore the antimicrobial potential of different parts of Tabebuia pallida. The methanol crude extract of different parts (leaves, stem bark, root bark and flowers) of the plant were used for screening antimicrobial potentials using disk diffusion and serial dilution method. Among the tested pathogens E. coli was highly susceptible to all parts of T. pallida except root extracts. Compare to other extract the flower part was highly sensitive against all tested pathogens with maximum zone of inhibition 21 mm. The MIC value 125 µg/ml of FE against E. coli was least in comparison to other part extracts and MBC was also similar to MIC value. In conclusion, the spectrum of activity suggests that methanol extracts of T. pallida flower could be a possible source to get noble and potential herbal medicines to treat infections, hence justified the ethnic uses of this plant against various infectious diseases.
