Abstract
The optimum extraction process was optimized with orthogonal design,investigating the influence of ethanol concentration,extracting time and the ratio of solid to liquid.Optimum extraction conditions were determined as follows:to blade,time 3 h,85% EtOH as extracting solvent,the ratio of solid to liquid 1 ∶5(g/mL),extracting for three times,the extraction rate of total paeoniflorin was 1.366%.
