摘要
用有机溶剂回流萃取八角精油。采用单因素和正交试验,得到溶剂回流法萃取八角精油的最佳工艺条件为:八角粉碎度为40~60目,回流时间为45min,回流温度95℃。在此条件下,八角精油得油率为27.1%,比水蒸气蒸馏法高出近8倍。通过两种方法的对比,结果显示溶剂回流法是萃取八角精油的一种较好的方法。
The reflux extraction of star anise oil was studied by orthogonal experiments based on single factor test.The best extraction conditions were designed as follows:grinding degree 40-60 mesh size,extraction time 45 minutes,and temperature 95 ℃.Under these conditions,extraction yield was 27.1%,which was eight times higher than that by steam-distilled extraction method.Compared with steam-distilled extraction method,the oil obtained by reflux extraction showed solvent showed better properties.
