This study used Box-Behnken Design （BBD）, a widely used form of response surface methodology （RSM）, to optimize the conditions of the ultrasound-assisted extraction （UAE） for the extraction of phenolic compounds from CimicifugaeRhizome. The influence of three independent variables, including ethanol concentration （%）, extraction time （min） and solvent-to-material ratio （mL/g）, on the extraction yields of phenolic compounds were examined. The results demonstrated that the optimal ultrasound-assisted extraction （UAE） conditions were as follows： ethanol concentration of 68%, an extraction time of 19 min, and solvent-to-material ratio of 30 mL/g for the extraction of caffeic acid, cimicifugoside, ferulic acid, isoferulicacid, cimifugin, 4′-O-β-glucopyranosyl-5-O-methylvisamminol. These results demonstrated the suitability of UAE for the extraction of phenolic compounds from CimicifugaeRhizome.展开更多
