摘　　要：以大红八角整果为原料,考察超临界CO2不同萃取条件对油树脂萃取及成分的影响.实验结果显示：超临界CO2萃取八角油树脂的最佳条件为原料粉碎后过1.50 mm孔径筛,萃取压力25 MPa,萃取温度55℃,萃取时间2.5 h（5L容积萃取釜,CO2体积流量50～60 L/h）.在此条件下,油树脂相对于原料的得率为12.83％,挥发油萃取效率为92.31％,用GC-MS方法对八角油树脂的挥发性成分进行了分析,其主要成分为反式茴香脑、D-柠檬烯、龙蒿脑等,反式茴香脑的相对含量为83.74％.The extraction of da-hong star anise oleoresin by supercritical fluid CO2 was studied.The results showed The optimum process parameters were as follows：mesh size was 1.50 mm,the pressure was 25 MPa and 55 ℃ for 2.5 h（extraction kettle of 5 L,the flow rate of CO2 was 55 L/h）.In this condition,the yield was 12.83％,the extraction rate was 92.31％.In addition,the volatile components of star anise oleoresin were analyzed by GC-MS.The main components were transanethole （83.74％）,D-Limonene,estragole,etc.
