The in vitro antibacterial activity of different extracts obtained from roots and rhizomes of Justicia tranquebariensis against different organisms namely Bacillus subtilis, Staphylococcus aureus, Escherichia coli and Klebsiella pneumonia have been carried out. The prepared extracts from petroleum ether and hydro alcohol (50:50) were investigated with different concentrations. Our findings showed that both extracts have highest
antibacterial activity in gram positive strains than gram negative strains. Also increase in concentration of each extract increases the antibacterial activity. Both the extracts showed  significant broad spectrum anti-bacterial activity.
