甲基乙二醛（methylglyoxal, MG），又称丙酮醛，是几种代谢途径产生的副产物，也是植物受到环境胁迫时产生的一种常见的有毒醛类化合物。高浓度的MG是一种细胞毒素，而低浓度的MG作为一种信号分子，调节细胞代谢、种子萌发、植物生长、发育、生殖等多种生理过程和耐逆性形成的获得，故 MG具有双重作用。 甲基乙二醛（MG）和1,2-邻苯二胺反应生成的产物在336nm下有最大吸收峰, 通过检测该产物在336nm的值进而计算得出样本中甲基乙二醛（MG）含量。
Methylglyoxal (MG), also known as pyruvaldehyde, is a byproduct of several metabolic pathways and a common toxic aldehyde compound produced by plants under environmental stress. High concentrations of MG act as a cytotoxin, whereas low concentrations of MG serve as a signaling molecule regulating various physiological processes such as cellular metabolism, seed germination, plant growth, development, reproduction, and the acquisition of stress tolerance. Thus, MG has a dual role. The product of the reaction between methylglyoxal (MG) and 1,2-diaminobenzene (o-phenylenediamine) exhibits a maximum absorption peak at 336 nm. The MG content in the sample is calculated by measuring the absorbance of this product at 336 nm.
