[Objective] To optimize the extraction technology of total flavonoids from HERBA CENTIPEDAE by orthogonal test. [Methods]Content of total flavonoids was detected by ultraviolet spectrophotometry. With the extraction rate of total flavonoids as the index,effects of enzymolysis time,pH value,cellulase concentration and enzymolysis temperature were researched. [Results] The optimal extraction technology was as follows: pH = 5,2. 5 h enzymolysis time,0. 3 mg / mL cellulase concentration and 37 ℃ enzymolysis temperature. Under this condition,the extraction rate of total flavonoids was 2. 814 7%. [Conclusions] This method was stable,easy and controllable,and provided references for the further development and utilization of HERBA CENTIPEDAE.
