Microwave-surfactant Extraction of Flavone from Trollius Chinensis Bunge was studied, choose SDS as significant surfactant, and extraction process was optimized by orthogonal experiment. The results showed that the optimum conditions for extracting was: SDS(?=0.75㎎／ml) as extraction agent, solvent amount of 40 ml／g Trollius Chinensis Bunge， microwave power of 600W, temperature of 70℃,extraction for 5 min. Under this condition, extraction rate can be up to 5.35%. Compared with traditional solvent, extraction time was decreased greatly, and extraction rate was increased about 30%.
