Objective： To optimize the extracting process of the total flavonoids from the fruit of Thladiantha Dubia Bunge. Method： The extract technology of the total flavonoids from the fruit of Thladiantha Dubia Bunge. was optimized by orthogonal experiment with the yield of total flavonoids as index and with the extraction number of times, extraction time, the ratio of solid to liquid as factors. Result ： The optimum extracting conditions for the total flavonoids from the fruit of Thladiantha Dubia Bunge. were as follows ： the reflux extraction was conducted twice （1.5 hour. time- 1 ） with 70% ethanol as solvent, and the ratio of solid to solution was 1： 8. Conclusion： The optimum extracting technology is simple, reproducible and stable.
