Abstract

Antimicrobial activity of aqueous extract of leaves of Cajanus cajan and capsicum annum on Staphylococcus aureus and Escherichia coli were investigated. C.cajan and C.annum contain alkaloids, tannins, saponins, Carbohydrates and proteins at varying levels. Antimicribial activity of C.cajan, C.annum and mixture of both was as follows. The kinetics of kill of individual cells by addition of extract of culture medium indicated decrease in the number of viable counts during the period of monitoring. Analysis of variance showed that there was no significant difference between the antimicrobial activity of standard antibiotic gentamicin and aqueous extract of C.cajan or or C.annum and the mixture of bith on the isolates. This results suggests that the aqueous extract C.cajan or or C.annum and the mixture of both have antimicrobial properties which can be pharmaceutically exploited.
