Attention is drawn to the development of a new and green alternative technique for the extraction of essential oils from spices. Solvent‐free microwave extraction (SFME) is a combination of dry distillation and microwave heating without added any solvent or water. SFME and hydrodistillation (HD) were compared for the extraction of essential oil from three spices: ajowan ( Carum ajowan , Apiaceae), cumin ( Cuminum cyminum , Umbelliferae), star anise ( Illicium anisatum , Illiciaceae). Better results have been obtained with the proposed method in terms of rapidity (1 h vs. 8 h), efciency and no solvent used. Furthermore, the SFME procedure yielded essential oils that could be analysed directly without any preliminary clean‐up or solvent exchange steps. Copyright © 2004 John Wiley & Sons, Ltd.
