Abstract:: With ginger as raw material，the ultrasonic extraction of flavonoids from ginger was studied.The extraction process of flavonoids was optimized with single factor experiment and orthogonal experiment，and the antibacterial activity of flavonoids from ginger was studied by filter paper method.The results showed that the optimum extraction conditions were determined as follows：alcohol concentration 80%，solid-liquid ratio 1∶12 g/mL，extraction temperature 50℃，extraction time 15 minutes.And ginger flavonoids showed different antibacterial activity for the four bacteria，the order of the strength of the inhibitory effect was Bacillus subitlis>Aspergillus niger>Penicillium>Escherichia coli.
