Abstract

Ohmic-assisted hydrodistillation (OAHD) is an advanced hydrodistillation (HD) technique utilizing ohmic heating process and could be considered as a novel method for the extraction of essential oils. One of the major problems with traditional methods is long extraction time. OAHD of essential oils from the aerial parts of Thymus vulgaris L. (common thyme) was studied and the results were compared with those of the conventional HD. The results showed that OAHD method had the extraction time of 24.75 min while this value was about 1 h for HD. Scanning electron micrographs of thyme leaves showed a sudden eruption of essential oil glands and their surrounding area for OAHD samples. GC–MS analysis did not indicate any noticeable changes in the compounds of the essential oils obtained by OAHD in comparison with HD. Results of this study introduced OAHD as a green technology because of less energy required per ml of essential oil extraction.
