Abstract�� To optimize extraction process of total flavonoids in Sanguisorba officinalis L.,the contents of total flavonoids and antibiotic action were considered,and the influences of extraction process on the antibacterial property of total flavonoids were tested.The optimum extracting procedure for total flavonoids were obtained: 20 g the drug and 150 mL 70% alcohol refluxing 2 hours each time for 3 times,the average extracting rate of the total flavonoids was about 10.25%.The optimized process was stable and workable.
