Abstract
Ethanolic extract from four medicinal plants, Justicia tranquebariensis, Tribullus terrestris, Aloe vera and Curcuma longa were tested for their antibacterial activity against four wound associated infectious microorganisms such as Staphylococcus aureus, Bacillus subtilis, E. coli and Klebsiella pneumonia by disc diffusion method. The Ethanolic stem extracts of Justicia tranquebariensis showed significant antibacterial activity against all test organisms. The spectrum of activity observed in the present study may be indicative of possible source of new and effective drugs from these herbals. The Ethanolic extracts of these four species were analyzed to identify electron transition and the functional group by FT–IR and UV Spectroscopy. The presence of the secondary alcohol, phenol, amines, alkanes and halogen has been revealed by FT-IR analysis. UV –VIS analysis of Justicia tranquebariensis, Tribullus terrestris and Curcuma longa confirm the presence of Aniline.
