Antibacterial and antidiarrheal activity of Butea Monospermea bark extract against waterborne enterobacter Cloacae in rodents: In-vitro, Ex-vivo and In-Vivo evidences.

Butea monosperma (Lam.) Taub. (family Leguminosae), popularly known as 'Palash' possess numerous medicinal properties since ancient times. According to the Wealth of India, stem bark of this plant exhibits various therapeutic properties like antimicrobial, astringent, styptic, aphrodisiac, and anti-inflammatory. The purpose of the present study was to investigate antibacterial and antidiarrheal effect of B. monosperma bark against newly isolated gram negative pathogenic bacterial strain Enterobacter cloacae. Aqueous extract of B. monosperma bark (BMAqE) was subjected to LC-MS/MS analysis for determination of bioactive components. Antibacterial study of BMAqE was assessed using bacterial growth kinetic study, fluorescence spectroscopy, outer and inner membrane permeability assay, dehydrogenase inhibitory assay and protein leakage assay followed by field emission scanning electron microscope (FE-SEM) study. Antidiarrheal activity was studied using castor oil induced diarrhea model in albino rats followed by histopathology studies of rat ileum. LC-MS/MS analysis of BMAqE revealed presence of twenty-two different active phytoconstituents out of which most of the constituents belong to flavonoid and polyphenol family. BMAqE showed MIC and MBC (IC BMAqE exhibits impressive antibacterial and anti-diarrheal activity and can be effectively used to eradicate water borne diseases.
