中文摘要: 对人参冻干超微粉的总皂苷微波辅助萃取工艺进行优化。试验结果表明人参总皂苷微波萃取的最优条件是：乙醇浓度为85%；萃取时间为25 min；萃取温度为60℃；料液比为1∶12（g/mL），萃取次数为3次。在此条件下人参总皂苷含量可达12.69 mg/L。微波萃取相比回流萃取法、索式萃取法、浸渍法和渗漉法，其人参总皂苷含量提高29%～41%，表明微波萃取人参中总皂苷是一种高效可行的制备方法。
Abstract:The process of microwave assisted extraction was used to extract ginsenoside from Ginseng powder by Freeze drying and superfine grinding.The optimum process conditions were as follows：ethanol concentration was 85%；microwave assisted extraction time was 25 min；material-solution ratio was 1∶12（g/mL）；microwave assisted extraction temperature was 60℃；times of microwave assisted extraction was 3.The content of total ginsenoside was up to 12.69 mg/L under above process conditions.The ginseng total saponin content by microwave assisted extraction increased by 29%-41%，compared with the content by the reflux extraction，Soxhlet extraction，soaking method and percolation method，so total saponins from Ginseng powder could be effectively extracted by microwave.
