摘　　要：采用超临界流体萃取技术提取甘草(Glycyrrhiza uralensis)中的角鲨烯,并用高效液相色谱法测定其含量。结果显示,在丙酮为夹带剂的萃取产物中角鲨烯含量高达0.47%,超临界流体萃取法对甘草角鲨烯的总提取率为0.018%,高于传统索氏提取法及超声辅助提取法所得提取率。Supercritical fluid extraction（SFE） was used to extract squalene from Glycyrrhiza uralensis;and the content was determined by HPLC.The content of squalene reached up to 0.47% when acetone was used as modifier;and the total yield reached 0.018%.The results showed that supercritical fluid extraction had advantage over traditional Soxhlet extraction and ultrasonic method for extracting squalene from G.uralensis.
