AbstractThis research work was aimed to separate ethanolic extract and cinnamalciehyde from Cinnamomum zeylanicum, The isolated compounds were used to study the inhibiting effect: on the growth of bacteria. These are Pseudomonas aemginosa, Escherichia coll, Proteus mirabilis, Salmonella typhi, Bacillus subtills, Staphylococcus aureus and Streptococcus pyogenes. The isolation was performed by using column chromatography packed with activated silica gel. Furthermore, die compound was identifloated by Tt.C plale technique and infrared spectroscopy (IK). Ethanolic extract showed strong inhibiting effect on B. sub/ifis and Ps. aeroginosa as compared with control samples (Tetracycline and Chloramphenicol). It showed effect inhibitory on E. coli, Salmonella typhi and Proteus mirabilis less than control samples. Also no clear effects on Staph, aureus and Strept. Pyogenes was indicated. Cinnamaldehyde showed stronger effects (compared with ethanolic extract) on E. coll, Ps, aeroginosa, Salmonella typhi and Ptroteus mirabilis in comparison to control samples. It showed effect on Strept. pyogenes equal to that of control samples, but no effects on Staph. aureus were observed.
