微波协同提取山茱英籽油工艺优化研究刘瑞林,王德金,袁静,郑伟婷,香生杰,詹文丽,张志琪(药用资源与天然药物化学教育部重点实验室,陕西师范大学化学化工学院,西安710062)摘要:研究以正己烷为溶剂超声一微波协同提取山茱英籽油的工艺
以出油率为指标,通过单因素实验分别考察了微波功率
超声功率
液料比
提取时间对山茱英籽油出油率的影响
以提取率为指标,利用Desin一expert软件设计正交试验,并用响应曲面优化法(RSM)优化山茱英籽油的提取工艺,确定的最佳提取工艺参数为:微波功率slow,超声功率350W

2、,液料比17:lm口g,提取时间10min
在此最佳条件下,山茱英籽油的一次提取率相对于索氏提取法为121.巧土0.09%(出油率为10.90士0.09%,n=3),与理论计算值12.6%基本一致,说明回归模型能较好地预测山茱英籽油的提取得率
试验结果表明,超声一微波协同提取山茱英籽油具有提取率高
速度快
操作简便等优点,另外为山茱英籽的进一步开发提供了参考依据
