ANTIMICROBIAL ACTIVITY OF PLANT BARK USED AS NATURAL CHEWING STICK AGAINST MOUTH FLORA AND LABORATORY BACTERIA

Antimicrobial activity denotes the inhibition activity or killing activity of chemical or extracts component against living organisms. Plants have the variety of these kinds of components which can be utilized to inhibit the pathogenic activity of some pathogens in our routine life. Here we took three plants (Neem, Babool and Miswak) bark which are used as chewing sticks, to make three different (Acetone, Methanol and Aqueous) extracts. By well diffusion method, these all extracts were checked against extracted mouth flora and common laboratory bacteria (E. coli, S. typhi, B. subtilis, P. vulgeris and Micrococcus). Phytochemical study of these bark juices were also done. Our data shows that the acetone extract of Babool is most effective among all other extract we tested.
