单萜类及其含氧衍生物是挥发油中低沸点物质,如果SFE-CO2提取挥发油的工艺选择不当,容易造成提取物中单萜类及其含氧衍生物含量显著降低。
Monoterpenes and their oxygen-containing derivatives are low-boiling substances in volatile oils. If the process of extracting volatile oils by SFE-CO2 is not properly selected, the contents of monoterpenes and their oxygen-containing derivatives in the extracts are likely to be significantly reduced.
