Antioxidant, Antibacterial, and Cytotoxic Activities of the Ethanolic Origanum vulgare Extract and Its Major Constituents

Figure 2

The cytotoxic effects of carvacrol, thymol, p-cymene, and 1-octacosanol in A549 cells. All experiments were repeated three times in two replicates as outlined in Section 2. The thymol and carvacrol concentrations are equimolar to those present in the ethanolic extract. (A) Significantly different from control, ; (B) significantly different from thymol-treated group, ; (C) significantly different from carvacrol-treated group, ; (D) significantly different from carvacrol + thymol + p-cymene + 1-octacosanol-treated group, .
