				        	Objective To optimize the extraction conditions for total flavonoids from Cibotium barometz by response surface meth-od(RSM). Methods According to the center combination of Box-Benhnken,using the RSM,the effects of ethanol concentration,the ratio of solid to liquid,the extraction time,and the extraction frequency were studied by central composite design. Results The opti-mal conditions of extraction were as follows:60%ethanol,the ratio of solid to liquid 1:40,refluxing and extracting twice,and 1.5 h for each time. Conclusion The actual extraction yield was 1.44%. The method of extraction has higher extraction efficiency than other methods and can provide a basis for the industrial production of the total flavonoids from S. barometz.
