Abstract To optimize extraction process of total flavonoids in Houttuynia cordata Thumb. by ultrasonic treatment, the contents of total flavonoids were used as markers, and the influence of ultrasonic treatment on the antibacterial property of total flavonoids was tested. The optimum extracting procedure for total flavonoids was the drug powder treated 10 min under 500 W, extracted by 60% alcohol with 10 times of the amount to drug weight, and the average extract rate of the total flavonoids was about 1.86%. The tests on antibiotic action show that the extracts by ultrosonic treatment have strong effect on five normal bacteria. The optimized process was stable, workable and applicable for industrial production.
