[目的]改变橘皮精油传统提取方法中的不足,为橘皮精油的进一步开发利用提供理论基础,也为橘皮的综合利用提供新途径.[方法]采用超临界CO2萃取与微波处理技术相结合萃取橘皮精油,就萃取时间、萃取压力、萃取温度和CO2流量等对橘皮精油提取率有较大影响的因素进行了探讨,并采用正交试验对试验方案进行了优化.[结果]影响橘皮精油得率的因素顺序为萃取时间＞萃取压力＞萃取温度＞CO2流量;当萃取时间为20 min、萃取压力为9.0 MPa、萃取温度为40 ℃和CO2流量为20 L/h时,精油的平均得率为2.08%.GC-MS的分析结果表明:橘皮精油中柠檬烯的含量最大,为55.65%,D-柠檬烯和β-松油烯次之,含量分别为6.12%和5.4...

[Objective] The theoretic basis and new approach of the development and utilization of essential oil of orange peel was provided through the improvement of the traditional technique of its extraction.[Method] The extraction time,pressure,temperature and CO2 flux and other factors affecting the extraction efficiency in the method of microwave and supercritical CO2 the extract of essential oil from orange peel was discussed and the extracting process was optimized with the orthogonal experiment.[Results] The results showed that the order of the f...
