This research explored the essential oil (EO) of Laurus nobilis. Various parameters were recorded, including the amount of yield, chemical composition and antioxidant activity. The EO was obtained by hydro-distillation (HD), hydro-steam distillation (HSD), microwave-assisted hydrodistillation (MAHD), and ohmic-assisted hydrodistillation (OAHD). The micromorphology of the plant leaves were studied under the different extraction methods. The yields of EOs obtained by the mentioned extraction methods were 1.40, 0.74, 1.00 and 0.83 (% w/w), respectively. The main chemical components in EOs obtained by these methods were eucalyptol (34.4–50.0%), α-terpinenyl acetate (14.9–18.8%), terpinene-4-ol (4.7–6.0%) and sabinene (4.9–5.9%). Two of the extraction methods, i.e. OAHD and MAHD, yielded EOs that contained higher proportions of eucalyptol. SEM images of the leaves were taken after extraction. It was …
