Antibacterial Activity of Tannins Extracted from Some Medicinal plants in vitro

Abstract

Abstract:Objective: To investigate the inhibition effect of some condensed tannins on the growth of four type of bacteria in vitro.Materials and methods: Susceptibilities were determined using diffusion method. Tests were conducted aerobically using AC agar medium. Results: The result indicate that source and concentration are importance factors that influence antimicrobial activity of tannin. Conclusion: Inhibition zones of growth were varied among plant seeds.
