Abstract
Mangroves have long been a source of biochemically unique and wide array of novel natural products. The anti-bacterial effect of different extracts of the plant Acanthus ilicifolius was determined in this study. The crude plant extracts of ethyl acetate, ethanol and methanol were tried against pathogenic microbes such as Aeromonas hydrophila, Vibrio harveyi and Escherichia coli using agar well diffusion mehod. All the three extracts of the various segments of the A. ilicifolius showed potent inhibition against tested microorganisms. The results conclude that the inhibitory zone showed by ethyl acetate was higher than that ethanol and methanol extracts.
Keywords: Acanthus ilicifolius, anti-bacterial effect, solvent extracts.
