Antioxidant potential of LR and BR in vitro. (A) antioxidant capacity (AOX) in human serum spiked with LR and BR (n = 15); (B) AOX of HSA spiked with Trolox, LR and BR (n = 15); (C) AOX of LR in HSA after its spontaneous degradation (initial LR concentration = 25 μmol/L) (n = 6); (D) lipoperoxidation (LPX) of brain tissue after addition of LR (dissolved in PBS) and BR (dissolved in DMSO) (n = 8); (E) LPX of brain tissue after addition of LR and BR dissolved in BSA (n = 8). *, p < 0.05; #, p < 0.001. LR, lumirubin; BR, bilirubin.
