The values obtained for DPPH-FRSA and total phenol content of oregano and rosemary essential oils are shown in Table 3. The FRSA of the studied essential oils exhibited a high inhibition percentage towards the free radical 2,2-diphenyl-1-picrylhydrazyl (DPPH). Oregano essential oil had a higher value(59.97%) than rosemary essential oil (48.23%). Kosar, Dorman, and Hiltuen (2005) reported lower FRSA in oregano (33%) and rosemary (20%) essential oils with respect tothe results observed in this study.
