Abstract

In general, food borne diseases may arise from the consumption of contaminated food due to microbials. Cinnamomum iners Reinw. ex Blume is belongs to the family of Lauraceae which used as traditional herb to cure fever and digestive problem. In this study, we evaluated the antimicrobial activity of leaf and bark extracted with ethanol, acetone and water. Two different concentrations (15 and 30μg) were used to compare the antimicrobial activity using in vitro disc diffusion zone. Five bacterial strains such Escherichia coli, Staphylococcus aureus, Serratia marcescens, Klebsiella pneumoniae and Pseudomonas aeroginosa and three fungal strains namely Trichophyton rubrum, Aspergillus fumigatus and Candida albicans were used. Bark extracts of C.iners exhibited higher inhibition zone against bacterial strains. Our present study concludes that bark extracts could be potential source to inhibit wide range of micro organisms than leaf extracts of C.iners.
