| Abstract: |
| In recent decades, the demand for medicinal plants has been increased due to the growing interest in natural products. Coriander (sativum Coriandrum L) is an annual and aromatic plant from the Apiaceae family with therapeutic and nutritional benefits. The plant is a rich source of aromatic compounds and essential oils, which have antibacterial, antifungal, and antioxidant effects. The extraction of essential oils from medicinal plants is usually done by distillation method. But some drawbacks such as high energy consumption, low yield, and long extraction time have created challenges in finding new extraction methods. In this study, the extraction of coriander seed essential oil using water distillation with ultrasound pre-treatment and traditional steam distillation methods was investigated. For this purpose, experiments were conducted at three levels of ultrasound power (300, 200, and 400 W) and three levels of ultrasound exposure time (15, 10, and 20 min), and a control sample were also examined. The results of statistical analysis showed that the effect of ultrasound power on the amount of extracted essential oil was not significant, but the effect of ultrasound exposure time on the amount of extracted essential oil was significant at a 1% level. The highest amount of extracted essential oil was observed at 200 W of power for 20 min, and the lowest amount was obtained at 200 W of power for 10 min. These findings can serve as a starting point for improving the extraction methods of coriander and other medicinal plants. |
