The present study was carried out to evaluate the antibacterial activity of bark, stem, root, leaf and fruit extracts from Terminalia arjuna on selected Gram positive and Gram negative bacterial strains. Aqueous extracts were used to evaluate the antibacterial activity. Phytochemical extracts from different parts of the plant exhibited significant anti-bacterial activity against tested microbial strains; however, inhibitory activities of the extracts were plant part and test organism dependent. Phytochemical extracts limited the growth of both Gram-positive and Gram-negative bacterial species tested however, Micrococcus luteus was less sensitive to the aqueous extracts. The results show that antimicrobial activity of phytochemical extracts of T. arjuna were concentration dependent (1.0 mg/disc and 5.0 mg/disc) on the bacterial strains tested. Further, the results depicts that bark extracts of T. arjuna could be used as a potential source of antimicrobial agents against the bacterial strains tested.
