摘要
探讨从花椒果实中萃取花椒精油的影响因素 .讨论了影响萃取率的实验条件 :即用无水乙醇作溶剂 ,采用回流方法 ,控制在 4 h提取效果较好 ,产率可达1 1 .84 % .产品既能保持花椒的原有风味 ,又能延长保质期和不含木质纤维且使用方便 .
The Xanthoxylin extracted from Zanthoxylum bungeanum Maxim fruit can keep its natural taste,prolong its quality life,contain no fibre of wood,also,be used conveniently.In this paper , various factors which affect the extraction were discussed.The results of experiment show that the extractive distillation method using ethanol absolute as solvent is a convenient one to obtain a good yield which might reach 11.84 percent at 78℃ for 4 hours.
