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.
Keywords: Antimicrobial activity, plant extract, Phytochemicals.
