中文摘要: 人参皂苷是人参中最重要的活性成分。通过超微粉碎联合超声波辅助提取技术制备了人参总皂苷。试验结果表明，超微粉碎后的人参微粉最小平均粒径可达到49.18 μm，只有粗粉的1/3到1/4，并可以显著提高人参中总皂苷的提取效率。人参总皂苷提取的最佳提取条件是人参平均粒径为69.48 μm，乙醇浓度为50%，超声功率为200 W，超声时间为40min，液固比为40∶1（mL/g），此条件下的总皂苷含量为8.564mg/100mL。
Abstract:Ginsenoside is the most important active ingredients in ginseng.The process of superfine grinding and ultrasound-assisted extraction was used to extract ginsenoside from ginseng.The minimal average particle size of ginseng reached to 49.18 μm by superfine grinding，only coarse powder of ginseng 1/3 to 1/4，and the efficiency of extraction of total ginsenoside was significantly improved.The optimum process conditions were as follows：the average particle size of ginseng was 69.48 μm；ethanol concentration was 50%；ultrasound time was 40 min，solution-material ratio was 40∶1（mL/g）；ultrasonic power was 200 W.The content of total ginsenoside was up to 8.564 mg/100 mL under above process conditions.
