1 Values are means ± SD, n = 6. Labeled means in a row with different letters differ, p < 0.05. A given 2 means labeled with # indicates a tendency, 0.05 ≤ p < 0.10. T-AOC, total antioxidative capacity; GPX, glutathione peroxidase; CAT, catalase; SOD, superoxide dismutase; MDA, malondialdehyde; PC, protein carbonyl.
