Objective- In the present work, we made an attempt to assess in vitro antibacterial activity of methanol extract of rhizome of Alocasia decipiens Schott of family Araceae against Staphylococcus aureus, Bacillus subtilis, Escherichia coli and Klebsiella sp. Method- Different concentrations of the methanolic extract (100%, 50%, 25% and 10%) were prepared and their antibacterial screening was carried out by modified filter paper disc method. The MIC of the extract was determined by the serial tube dilution method. The selected microorganisms were also tested against different antibiotics (10mcg/disc). Results- The present experiment showed that methanol extract at 100% concentration showed significant result against the test organisms where Staphylococcus aureus was observed as the most sensitive (16mm) and Klebsiella sp. was found to be the resistant one. Zone of inhibition observed, against different test organisms were also supported by the results obtained from MIC. Conclusion- Our experiment proposes Alocas...
