Evaluation of antibacterial properties of Musa paradisiaca L. Leaves

Musa paradisiaca L The antibacterial activity of plants have been screened because of their great medicinal relevance with the recent years, infections have increased to a great extent and resistant against antibiotics, becomes an ever increasing therapeutic problem. Musa paradisiaca L. cv. Puttabale is very common plant known as banana plant belonging to Musaceae family. Traditionally leaves of banana plant are used to serve food. Aim of present study is to evaluate Musa paradisiaca L. (banana) leaves for antibacterial study. Solvents like petroleum ether, chloroform, ethanol are used to prepare leaf extract of Musa paradisiaca L. with the help of Soxhlet apparatus. Antibacterial activity of leaf extract was screened against four different bacterial strains Bacillus subtilis (NCTC8236), Escherichia coli (ATCC25922), Pseudomonas aeruginosa (ATCC27853) and Staphylococcus aureus (NCTC25953) by agar diffusion method and compared with standard drug Ciprofloxacin a well-known broad-spectrum antibacterial agent. The ethanol extracts of Musa paradisiaca showed the broad spectrum of antibacterial activity on the tested microorganisms with high inhibitory potency against Escherichia coli and Staphylococcus aureus
