Antimicrobial activity of leaf extract of Henckelia humboldtiana (Gesneriaceae) was studied using different solvents like chloroform, acetone, ethanol and aqueous against 13 bacterial strains. The antimicrobial activity was determined by disc diffusion method. Out of the four extracts used, ethanol and aqueous extracts were found to be highly active against most of the bacterial strains while acetone extract was less active, while the chloroform extract was found to be nil or negative action against all the 13 test microorganism. The data clearly proves that the crude extract of Henckelia humboldtiana exhibit strong inhibitory action against most of the test bacterial pathogens.
