Abstract
Tecoma stans stem bark possesses a substantial amount of polyphenolic antimicrobial compounds that can be used for controlling the growth of pathogenic microorganisms. The purpose of this study was to assess antibacterial and antifungal activity of Tecoma stans stem bark extracts against antibiotic-resistant pathogenic bacteria and toxin producing molds, respectively. Tecoma stans stem bark was subjected to polyphenolic extraction using different solvents viz., water, ethanol, acetone, and methanol. Antibiotic-resistant strains of Staphylococcus aureus, Enterococcus faecalis, Enterobacter aerogenes, Salmonella typhimurium, and Escherichia coli were screened for the antibacterial activity of different grape extracts. Antibacterial activity was analyzed using agar well diffusion method. Penicilliumchrysogenum, Penicilliumexpansum, Aspergillusniger and Aspergillusversicolor were screened for the antifungal activity. Antifungal activity was determined by counting nongerminated spores in the presence of peel extracts. As compared to other solvent extracts, methanol extracts possessed high antibacterial and antifungal activity. S.typhimurium and E. coli showed complete resistance against antibacterial action at screened concentrations of grape peel extracts. Maximum zone of inhibition was found in case of S.aureus, i.e., 22 mm followed by E.faecalis and E.aerogenes, i.e., 18 and 21 mm, respectively, at 1080 mg tannic acid equivalent (TAE)/ml. The maximum and minimum percent of growth inhibition was shown by P.expansum and A.niger as 73% and 15% at 1080 TAE/ml concentration of grape peel extract, respectively. Except S.typhimurium and E.coli, growth of all bacterial and mold species were found to be significantly (P < 0.05) inhibited by all the solvent extracts.
