Abstract
The purpose of this study is to investigate the relationship between the methycellulose (MC) and ethylcellulose (EC) of encapsulated C. odorata extracts (methanol and ethanol) and their antimicrobial properties against E. coli and Staphylococcus aureus. The encapsulated of C. odorata extract was prepared by solvent displacement method through dialysis tube cellulose membrane and it was freeze-dried to obtain the suspension of encapsulated C. odorata extract. Then, antimicrobial properties of encapsulated C. odorata extracts was performed by broth dilution method on target bacteria. A few drops of hydrochloric acid (HCl) were added into growth media until pH 4 to mimic the acidic conditions in human stomach. The results showed the encapsulated methylcellulose of methanol extract (MC-M) inhibit both bacteria types.
