Abstract: The antibacterial activities of 12 natural citral derivatives against Escherichia coli, Staphylococcus aureus, Staphylococcus epidermidis, Pseudomonas aeruginosa were evaluated through anti-bacterium-circles and two-fold agar dilution methods. The results showed that these citral derivatives all had antibacterial effect on four bacteria. Geranyl isobutyrate exhibited the strongest effect on E. coli, with the diameter of antibacterial circle 14.83 mm and MIC 8 mg·L-1; Nerol strongest on S. aureus and S. epidermidis, with the diameters of antibacterial circle 15.80 and 14.33 mm and the MIC 8 and 16 mg·L-1; Geraniol best on P. aeruginosa, with the diameter of antibacterial circle 15.00 mm and MIC 16 mg·L-1. The relative permeability of bacterial’s cytomembrane was measured, and the result showed that the relative permeability increased after treated by the citral derivatives, which implied that these citral derivatives had a destructive effect on the bacterial cytomembrane.
