In this article, we used ethanol solution as extrat solvent, according to single-factor experiments, optimizating the extraction technology of antioxidants from Elatostema involuratum Franch.et Sav. by response surface methodology (RSM). The optimum extraction conditions of antioxidants from Elatostema involuratum Franch.et Sav. were obtained as follows:the concentration of ethanol 51%, liquid/solid ratio 20∶1 (mL∶g), extraction time 50 min, extraction temperature 85℃, extraction times twice, the yield of antioxidants were 1.405%under this condition. And the yield of antioxidants from leaves and stalks were 3.048%, 0.516%, respectively.
