摘要
利用超临界CO2萃取技术对沉香叶中挥发油提取的最优工艺进行研究,正交试验结果表明,在萃取温度为30℃、萃取压力为18MPa、萃取时间为2h的条件下,挥发油萃取率1.296%为最高值。采用超临界CO2萃取沉香叶挥发油与传统的水蒸气法提取方法相比,萃取效率更高,分离效果更佳明显。
The process of Aquilaria sinensis leaves essential oils extracted by supercritical CO2 extraction technology was studied.As the orthogonal experiment shown,the optimal conditions were as follows：extraction temperature 30℃,pressure 18MPa,extraction time 2h.Under this condition,the highest extraction rate of 1.296％ was obtained.A.sinensis leaves essential oils extracted by supercritical CO2 extraction technology had higher extraction efficiency and better separation effect comparing with the traditional steam extraction method.
