Abstract
Ancient Indian literature mentions many indigenous medicinal plants, claimed to posses antimicrobial activity and wound healing property. Specific and detailed investigations to prove their efficacy however, appear to be meagre. Leaves of Azadirachta indica, Annona squamosa, Ocimum sanctum and leaves and stems of Bergia odorata were dried in shade, pulverised to homogenous powder, and proximate chemical analysis was done. Solidified chloroform extracts of all plants dissolved in propylene glycol were used for in vitro inhibition of microbial growth on Staphylococcus aureus, Streptococcus pyogenes, Corynebacterium spp. Escherichia coli and Pseudomonas aeruginosa by 10 fold serial dilution of incubated 5 ml. Glucose broth containing 0.1 ml extract and 0.1 ml inoculum of each organism, and subsequent plating by standard plate count method (SPC).
