摘　　要：以广西国有雅长林场二沟分场的八角干果为原料,经粉碎后,采用不同溶剂、不同提取法提取八角油树脂,并进行了单因素、正交优化试验。结果表明:在几种溶剂实验中,丙酮与无水乙醇混合作为溶剂效果较好,得出的平均产率为35.09%;采用索氏提取法比回流法提取率高,平均产率为25.03%,回流法得出的平均产率仅为13.97%。Taking nuts of Illicium verum in Ergou Sub‐Farm in Guangxi Yachang State‐Owned Forest Farm as raw materials ,star anise oil resins were extracted by adopting different solvents and different extraction methods after crushing .Result shows that among several solvent experiments ,it is optimal by taking acetone & ethanol as a sol‐vent ,and the average yield are 35 .09% ;the average yield (25 .03% ) by using Soxhlet extraction is higher than that (13 .97% ) by using reflux extraction .
