Headspace single drop microextraction (HS-SDME) coupled with microwave extraction (ME) was developed and applied to the extraction of the essential oil from dried Syzygium aromaticum (L.) Merr. et Perry and Cuminum cyminum L. The operational parameters, such as microdrop volume, microwave absorption medium (MAM), extraction time, and microwave power were optimized. Ten microliters of decane was used as the microextraction solvent. Ionic liquid and carbonyl iron powder were used as MAM. The extraction time was less than 7 min at the microwave power of 440 W. The proposed method was compared with hydrodistillation (HD). There were no obvious differences in the constituents of essential oils obtained by the two methods.
顶空单滴微萃取（HS-SDME）结合微波萃取（ME）被开发并应用于从干燥的丁香（Syzygium aromaticum（L.）Merr. et Perry）和孜然（Cuminum cyminum L.）中提取精油。优化了操作参数，如微滴体积、微波吸收介质（MAM）、萃取时间和微波功率。使用 10 微升癸烷作为微萃取溶剂。离子液体和羰基铁粉用作 MAM。在微波功率为 440 W 的情况下，萃取时间小于 7 分钟。该方法与水蒸馏（HD）进行了比较。两种方法得到的精油成分没有明显差异。
