Fig 6. Naringenin (NGN) containing formulation inhibits superoxide anion generation and lipid peroxidation induced by UVB irradiation.

(A) Superoxide anion production was measured by nitroblue tetrazolium (NBT) reduction assay in samples collected 2 h after the end of irradiation. (B) Lipid peroxidation was measured by tert-butyl hydroperoxide-(LOOH) initiated chemiluminescence (QL) assay in samples collected 4 h after the end of irradiation. Bars represent means ± SEM of 5 mice per group per experiment and are representative of two separate experiments. *p<0.05 compared to the non-irradiated control groups (white bars); #p<0.05 compared to the irradiated control groups (black bars).
