Ionic liquid was used as microwave absorption medium and applied to the extraction of essential oils from dried fruits of the Illicium verum Hook. f. and Cuminum cyminum L. by microwave-assisted extraction. The extraction time is less than 15 min at the microwave power of 440 W. The constituents of essential oils obtained by the proposed method were compared with those obtained by hydrodistillation. There is no obvious difference in the constituents of essential oils obtained by the two methods.
离子液体被用作微波吸收介质，并应用于微波辅助提取八角和孜然果实干中的精油。在微波功率为 440 W 的情况下，提取时间不到 15 分钟。所提出的方法获得的精油成分与水蒸馏法获得的精油成分进行了比较。两种方法得到的精油成分没有明显差异。
