MDA content was measured as described
by Feng et al.with minor modification [12]. The 0.5 g fresh samplewas
extractedwith 6 mLof 10% (w/v) trichloroacetic acid (TCA). The
homogenate was centrifuged at 4000 ×g for 10 min. 1 mL supernatant
and 1 mL TCA were added to 2 mL of 20% TBA solution containing
0.6% (w/v) thiobarbituric acid.
