Optimization of Aralia chinensis L.saponin extraction process
OBJECTIVE To optimize the extraction process of total saponins from Aralia chinensis L.METHODS The extraction process of Aralia chinensis L.saponin was optimized by one-way and response surface design using solvent concentration,extraction time,liquid/feed ratio and extraction temperature as the influencing factors.RESULTS The results showed that the optimal extraction process of Aralia chinensis L.saponin was based on the ethanol concentration of 70%,extraction time of 80min,liquid/feed ratio of 20.4(mL∶g),and extraction temperature of 74℃,and the content of aralia total saponin was 9.74%.CONCLUSION The process is stable,reliable,simple and feasible,and provides scientific basis for further comprehensive development and utilization of Aralia chinensis L.herbs.
