Abstract:Objective To investigate the anti-endotoxin, antibacterial and anti-inflammatory effects of Ilicis chinensis folium water decoction (ICFWD) and reveal the pharmacological properties of the clearing-heat and detoxifying effects of Ilicis chinensis folium. Methods The anti-endotoxin effect of ICFWD in vitro was tested using the limulus agglutination assay. Antibacterial effect for the combination of ICFWD in vitro with cefotaxime, levofloxacin and gentamicin against 25 strains including methicillin-sensitive Staphylococcus aureus (MSSA), methicillin-resistant Staphylococcus aureus (MRSA), ESBLs-producing Escherichia coli, non-ESBLs-producing Escherichia coli, and Pseudomonas aeruginosa (P. aeruginosa) were also investigated by the agar 2-fold dilution assay. The anti-inflammatory effect of ICFWD was observed by an xylene-induced auricle inflammation model in mice. Results ICFWD showed anti-endotoxin effects at doses ranging from 6.25 to 100mg/mL. The minimum inhibitory concentration of ICFWD against MSSA and MRSA, ESBLs-producing Escherichia coli, non-ESBLs-producing Escherichia coli, as well as P. aeruginosa were 8~33mg/mL, 33~>133mg/mL and 33~133mg/mL, respectively. The combined treatment of ICFWD with cefotaxime, levofloxacin and gentamicin showed additive effects, the fractional inhibitory concentration (FIC) index were 0.5
