EVALUATION OF ANTIBACTERIAL ACTIVITY OF SOME INDIAN MEDICINAL PLANTSSUMATHI AND PUSHPA
Ten bacterial isolates were tested for their sensitivity against standard antibiotics, aqueous and alcoholic extracts of the five plant samples and the mixture. E.cloacacea used in the study was multidrug resistant strain. Only the growth of E.coli was inhibited by the aqueous extracts of Acalypha indica and Mollugo latoides while the other aqueous extracts were inert. The aqueous extracts of Acalypha indica and Mollugo latoides were found to be effective in inhibiting the growth of E.coli at a concentration of 12.5 mg/mL and 6.25 mg/mL respectively. The MIC of alcoholic extracts of Nelumbo nucifera was found to be 0.390 mg/ mL for K.pneumoniae. All the plant extracts showed promising antibacterial properties but the alcoholic extracts exerted greater antibacterial activity than aqueous extracts.
