Furthermore, the antibacterial activities of the essential oils and their constituents against 9 strains of bacteria, including Escherichia coli, Pseudomonas aeruginosa, Enterococcus faecalis, Staphylococcus aureus, Staphylococcus epidermidi, Methicillin-resistant Staphylococcus aureus, Klebstitlla pneumoniae, Salmonella sp., and Vibrio parahemolyticus were investigated. In addition, the antibacterial activities of cinnamaldehyde congeners were also examined to help understand the effects of chemical structure on the antibacterial activity. It is expected to find the environmentally friendly bioactive constituents from the indigenous species.土肉桂葉子精油桂皮醛抗細菌活性Cinnamomum osmophloeumLeafEssential oilCinnamaldehydeAntibacterial activity
