Abstract: The antibacterial activities of burdock roots against Vibrio parahemolyticus were investigated. The peel and peeled root of two varieties of burdock named Liuchuan and Huangji were extracted with 80% ethanol, classed as LP, LR, HP and HR respectively. The data from disk diffusion method and minimum inhibitory concentration (MIC) values showed that the antibacterial activity of LP was more significant than that of LR, HP and HR. The time–kill study indicated that V. parahemolyticus was reduced to non-detectable levels with 1000 μL/mL LP extract treatment at 4 and 25 ℃ for 7 h in DW and no bacteria cell was detected with all treatment on Day 1 at 4 and 25 ℃ in BHI. Basing on its good antibacterial activitiy, LP could be useful in control of V. parahemolyticus.
