Antioxidant Capacity. Antioxidant capacity levels were not significantly (p < 0.05) altered following UVA or UVB exposure; however, treatment with pomegranate polyphenolics at concentrations greater than 50 mg/L significantly increased the antioxidant capacity levels in a dose-dependent manner (Figure 3). Conversely, UV exposure did not affect the antioxidant capacity. Intracellular antioxidant enzymes, responsible for neutralizing reactive species, may have contributed to maintaining the antioxidant capacity after treatment with UV (9). Higher doses of pomegranate may have acted through counteracting UV-induced generation of ROS and/or increasing the antioxidant activity of cells. Both mechanisms may confer extra protection to cells when longer UV exposure time is used.
