Gas chromatography - Mass spectrometry analysis and antibacterial activity of Cinnamomum burmanii essential oil to Staphylococcus aureus and Escherichia coli by gaseous contact

Infectious diseases and antibiotic resistance becomes a problem that must be resolved. Plant based products are among the alternative agents examined in order to replace conventional antibiotics. Cinnamaldehyde is one of the compound in cinnamon oil that has antibacterial activity. But the other compounds in cinnamon oil has also the potential antibacterial activity. The purpose of this study to conduct GC-MS analysis of cinnamon oil and its antibacterial activity to Staphylococcus aureus and Escherichia coli by gaseous contact. Cinnamomum burmannii was distilled by water-steam distillation to obtain essential oil. Identification of compounds was analyzed by GC-MS. Antibacterial activity was observed by gaseous contact method in airtight boxes. The GC-MS analyzed showed that there are four major compounds of cinnamon oil, trans-cinnamaldehyde (56,10%), 1,8-cineole (16,53%), α-pinene (3,44%) and α –terpineol (3,05%). The Minimum Inhibitory Dose (MID) of cinnamon oil to E. coli and S. aureus was 12.5 µL/L a...
