چکیده :

The current research was carried out to reveal the possible impacts of cold plasma on essential oil (EO) content and composition of cumin (Cuminum cyminum L.), as a new approach in medicinal plants processing. Cumin seeds were exposed to plasma at different voltages (17, 19, 21, and 23 kV). The EO content was determined using hydro-distillation, and the compositions of the extracted EOs were quantified using gas chromatography and gas chromatography-mass spectrometry techniques. The results showed that with increasing voltage intensity from 17 to 23 (kV), the hydrophilicity of cumin seeds and EO content (extraction efficiency) increased. Also, %25 color change was observed between the control and the treated samples. Major constituents of EO included β-pinene (%5.5-12.2), p-cymene (%8-11.2), (E)-beta-ocimene (%15.7), cumin aldehyde (%23.9-47.6), γ-terpinene (%25.3-37.5). The EO analysis results showed that cumin aldehyde was reduced by %20 compared to the control sample.
