Response Surface Method was applied to optimize the Ultrasound-assisted extraction of the total flavonoids from Rhododendron. On the basis of single factor experiments, the optimum conditions for the Ultrasound-assisted extraction of flavonoids from Rhododendron were obtained through Box-Benhnken center-united experiment design and Response Surface Method with 3 factors and 3 level. On the analysis of various factors significant and interaction, the optimum Ultrasound-assisted extraction conditions of flavonoids from Rhododendron were as follows:the ethanol content is 74.08%, the ratio of solid to liquid is 20.58∶1 and extraction time is 32.48 min.Under such condition, the average extraction rate could be up to 8.758%.
