Microwave‐assisted extraction of bioactive components from Angelica dahurica using the tailor‐made natural deep eutectic solvents

In the present study, a new, green, efficient, and sustainable microwave-assisted extraction method combined with a deep eutectic solvent was successfully established for the extraction of five important coumarins from Angelica dahurica, namely bergapten, oxypeucedanin, imperatorin, cnidilin, and isoimperatorin. Compared with the conventional extraction method, the extraction efficiency of this method was improved by 10.74%. With increasingly serious global environmental pollution, this green method will be a solution for mainstream sustainable development and lead to a stable improvement in fine industries such as food, medicine, and cosmetics. The findings of this study may provide valuable clues and a scientific basis for further research of A. dahurica and other pharmaceutical components.
