摘要
目的优化楤木中总皂苷的提取工艺.方法以提取溶剂浓度、提取时间、液料比、提取温度为影响因素,采用单因素和响应面设计实验优化楤木皂苷的提取工艺.结果楤木皂苷最佳提取条件为乙醇浓度70％、提取时间80min、液料比20.4(mL∶g)、提取温度74℃,该工艺条件下得到楤木总皂苷含量为9.74％;结论该工艺稳定可靠,操作简单可行,为进一步综合开发利用楤木药材提供科学依据.
Abstract
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.
