1Antibacterial and antioxidant activities of Musa sp.leaf extracts against multidrug resistant clinical pathogens causing nosocomial infection显示文摘Objective:To investigate different Musa sp.leave extracts of hexane,ethyl acetate and methanol were evaluated for antibacterial activity against multi-drug resistant pathogens causing nosocomial infection by agar well diffusion method and also antioxidant activities.Methods:The four different Musa species leaves were extracted with hexane,ethyl acetate and methanol.Antibacterial susceptibility test,minimum inhibitory concentration and minimum inhibitory bacterial concentration were determined by agar well diffusion method.Total phenolic content and in vitro antioxidant activity was determined.Results:All the Musa sp.extracts showed moderate antibacterial activities expect Musa paradisiaca with the inhibition zone ranging from 8.0 to 18.6 mm.Among four species ethyl acetate extracts of Musa paradisiaca showed highest activity against tested pathogens particularly E.coli,P.aeruginosa and Citrobacter sp.The minimum inhibitory concentrations were within the value of 15.63-250μg/ml.and minimum bactericidal concentrations were ranging from 31.25-250μg/mL.Antioxidant activity of Musa acuminate exhibited maximum activity among other three Musa species.Conclusions:The present study concluded that among the different Musa species,Musa paradisiaca displayed efficient antibacterial activity followed by Musa acuminata against multidrug resistant nosocomial infection causing pathogens.Further,an extensive study is needed to identify the bioactive compounds,mode of action and toxic effect in.vivo of Musa sp.Ponmurugan Karuppiah Muhammed Mustaffa 2013Asian Pacific Journal of Tropical Biomedicine2013,3,9:1
