In this study, two methods of Carum copticum essential oil extraction were examined. Traditional hydrodistillation (TH) and innovative Ultrasonic Ohmic Hydrodistillator (UOH) methods have been compared and evaluated for their effectiveness in the isolation of essential oil. The UOH offers main advantages over TH, namely: shorter isolation time (20 min against 2.5 h for TH), higher quality and quantity of essential oil, higher antioxidant activity and somewhat lower operating and energy cost. Based on the present study, the UOH process may be considered to have a significant potential in the field of extraction of essential oils from seeds and herbs.
