Evaluation the Antibacterial Properties of Different Extracts of Cinnamomum zeylanicum Barks

摘要

Antibacterial activities of different concentrations of methanolic and chloroform Cinnamomum zeylanicum bark extract were studied against a number of pathogenic isolates included Streptococcus pyogenes, Enterococcus faecalis and Escherichia coli and compared with ampicillin using agar well diffusion method. Two types of solvents were used for extraction, methanol and chloroform, with different concentrations (100μg/μl,150μg/μl, and 200μg/μl) for each extract were used. The results revealed that the pattern of inhibition varied with the solvent used for extraction and concentration. Extract that prepared in methanol provided more antibacterial activity as compared to chloroform extract against all tested bacteria at all concentrations, where the Streptococcus pyogenes was more susceptible than and Enterococcus faecalis and Escherichia coli respectively to both extracts. Results of the present study sign the interesting assurance of designing an active antibacterial agent from Cinnamomum zeylanicum bark.
