Effects of astaxanthin on antioxidant capacity of golden pompano (Trachinotus ovatus) in vivo and in vitro

Table 5 The antioxidant statuses of hepatocytes treated with or without astaxanthin and H₂O₂ supplementation

	T-AOC (U/mg protein)	SOD (U/mg protein)	GSH (μmol/g protein)	MDA (nmol/mg protein)
Control	0.35 ± 0.01b	2682.76 ± 127.04b	17.81 ± 0.83b	0.13 ± 0.01a
H₂O₂	0.22 ± 0.02a	3264.92 ± 76.26c	5.92 ± 0.91a	0.40 ± 0.01c
H₂O₂ + AST	0.37 ± 0.01bc	2726.34 ± 74.17b	28.24 ± 1.11c	0.23 ± 0.01bc
AST	0.41 ± 0.01c	2312.19 ± 69.94a	136.51 ± 4.11d	0.12 ± 0.01a

Values are mean ± SEM of three replicates, and values in the same column with different letters are significant different (P < 0.05). Control meant golden pompano groups fed diets without supplementation of astaxanthin (AST). Control groups meant treating with neither H₂O₂ nor AST, H₂O₂ groups meant treating with H₂O₂ only, H₂O₂ + AST groups meant treating with both H₂O₂ and AST, and AST groups meant treating with AST only
T-AOC total antioxidant capacity, GSH reduced glutathione, SOD superoxide dismutase, MDA malondialdehyde
