ABSTRACT
In the present study aqueous, ethanolic and methonolic extract of Azima tetracantha were investigated for antimicrobial activity. The microorganisms employed were Klebsiella sp, Staphylococcus aureus and Pseudomonas aeruginosa. sp. The susceptibility of bacteria strains against the three extracts was determined using the well diffusion method. The most susceptible micro organisms was Staphylococcus aureus while the least susceptible was Klebsiella sp. Highest antibacterial activity was observed with water extract of Azima tetracantha against S. aureus while minimum activity was observed with extract of Azima tetracantha against Klebsiella sp. Phytochemical analyses revealed the presence of alkaloid, tannin, Phenol, valotile oil, steroid, tannin and saponin.
Keywords: Azima tetracantha, Staphylococcus aureus and Pseudomonas aeruginosa. sp.
