Analysis Of Bacteriostatic And Bactericidal Activity Of Sphenocentrum Jollyanum Roots (chewing Sticks) On Some Human Pathogenic Bacteria

  ABSTRACT  Methanol and Aqueous extract of Sphenocentrum jollyanum roots (chewing stick) were screened for their antibacterial activity against E. coli, P. mirabilis, S. aureus and K. pneumoniae. Different concentrations were used (0.1, 0.2, 0.5 and 1mg/disc) to evaluate the roots extracts using disc diffusion and broth dilution method. The results showed that only methanol extract of Sphenocentrum jollyanum roots was effective against all the organisms tested. In disc diffusion method, there was a gradual increase in activity as the concentration increases from 0.1 – 1mg/disc. Similar patter…
