Musa sapientum (M.sapientum) commonly known as 'banana' is widely used in Bangladeshi folk medicine for the treatment of various ailments including diarrhea. Hence, the present study was designed to investigate antidiarrheal, antioxidant and antibacterial potential of the methanolic extract of M.sapientum seed (MMSS). The extract was studied for antidiarrheal property using castor oil and magnesium sulfate induced diarrheal model and charcoal induced gastrointestinal motility test in mice. Total phenolic and flavonoids content, total antioxidant activity, scavenging of 1,1-diphenyl-2-picrylhydrazyl (DPPH) radical, as well as nitric oxide (NO) and assessment of reducing power were used to evaluate antioxidant potential of MMSS. In addition, disc diffusion methods were used for antibacterial assay using various diarrheal induced bacterial strains. At the doses of 100 and 200 mg/kg body weight, the extract reduced the frequency and severity of diarrhea in test animals throughout the study period. At the same doses, the extracts significantly (p<0.001) delayed the intestinal transit of charcoal meal in test animals as compared to the control. In DPPH and NO scavenging method, MMSS showed good antioxidant potentiality in a dose dependent manner with the IC50 value of 12.32±0.33 μg/ml and 18.96±1.01 μg/ml, respectively with a significant (p<0.001) good reducing power. The extract also displayed strong antibacterial effect against when tested against Escherichia coli, Shigella dysenteriae, and Pseudomonas aeruginosa. Altogether, these results suggest that the MMSS could be used as a potential antidiarrheal agent along with its antioxidant and antibacterial potentiality.
