Antibacterial Analysis of Foeniculum Vulgare (Fennel)

Abstract

For chemotherapist the great objective is development of new antibiotic drugs from plant source. Plants contain many diverse complex compounds. In the past decades many plant exracts, essential oils, secondary metabolites and new synthesised molecules work as potential antimicrobial agents. To evaluate antimicrobial activity of plant extracts many workers used agar well diffusion method. The present investigation was performed for antimicrobial analysis of fennel. The antimicrobial activity of spice extracted in acetone, methanol and benzene was tested against Staphylococcus aureus, Enterobacter aerogenes, Escherichia coli and Pseudomonas aeruginosa. The maximum zone of inhibition was against Pseudomonas aeruginosa for both benzene and acetone extract (17mm) at the concentration 100 l/ml. All extracts showed least activity against Escherichia coli bacteria.
