摘要
分别用超临界CO 2萃取法和乙醚超声萃取法提取皇帝柑果皮挥发油,并比较两种提取方法得到的皇帝柑果皮挥发油成分上的差异.结果显示,采用超临界CO 2法提取的挥发油得率为0.75%,被鉴定的成分有28种,D-柠檬烯含量为45.24%;乙醚超声法提取的挥发油得率为0.69%,被鉴定的成分有24种,D-柠檬烯含量为37.73%.两种提取方法所得的皇帝柑果皮挥发油既有相同成分也有不同成分,但含量上存在较明显的区别.超临界CO 2萃取法较乙醚超声萃取法挥发油的出油率更高,鉴别出的成分更全面,有效成分含量也更高.
Supercritical CO 2 extraction and ether ultrasonic extraction were used to extract volatile oil from peels of emperor orange.The components of the volatile oil obtained by the two methods were compared,showing that the yield of volatile oil extracted by supercritical CO 2 method was 0.75%,and 28 components were identified,in which d-limonene was 45.24%;the yield of volatile oil was 0.69%by ether ultrasonic extraction,and 24 components were identified,in which d-limonene was 37.73%.Volatile oil extracted from emperor orange peels obtained by the two extraction methods had both the same and different components,and obvious difference on content.Compared with ether ultrasonic extraction,supercritical CO 2 extraction had higher yield of volatile oil,more comprehensive components and higher active ingredient content.
