OBJECTIVE To discuss the feasibility of the accelerated solvent extraction(ASE) for paeoniflorin.METHODS Different factors and levels were investigated by method of single factor.RESULTS The most favorable conditions of extraction process were as follows:the concentration of alcohol was 50%,the temperature was 100℃,the pressure was 50 kg,the velocity flow was 0.7 ml·min~(-1),the extraction time was 12 min,and the collected volume was 8 ml.CONCLUSION The ASE could extract paeoniflorin from Radix Paconiae rub...
