Comparison between MDA levels determined by the proposed UPLC-MS/MS method and the traditional TBARS method.

Sample type	MDA level (µg/g fresh weight)
	UPLC-MS/MS	TBARS
Control	1.10 ± 0.03	3.6 ± 0.1
Stressed	3.5 ± 0.1	4.7 ± 0.2

and letters represent statistically different MDA concentration levels (.0027, ), while the letter represents average MDA values that were not statistically different (.2087, ).
