Abstract

In the present work, the roots of Musa Paradisiaca Lam. (Family: Musaceae) were investigated for preliminary phytochemical screening and antibacterial activity. Preliminary phytochemical screening of ethanol extract of the roots revealed the presence of various classes of compounds like alkaloids, glycosides, steroids, flavonoids, saponins, reducing sugars and tannins. The ethanol extract of the roots of Musa Paradisiaca Lam. was tested by using agar disc diffusion method for antimicrobial assay. The ethanol extract of Musa Paradisiaca Lam. showed moderate in-vitro antibacterial activity against both gram positive (B. Megaterium, B. Subtilis, S. aureus) and gram negative (E. coli, P. aeruginosa, S. dysenteriae, S. typhi, Vibrio cholerae and S. flexneri) bacteria with the zones of inhibition ranging from 10.53 ± 0.37 to 12.42 ± 0.85 mm at concentration of 500 µg/disc. Thus the findings revealed the medicinal potential of Musa Paradisiaca Lam. against various infectious diseases to develop a drug.
