丙二醛（MDA）是生物体在衰老或逆境胁迫下，组织或器官膜脂质发生过氧化反应的终产物之一，其含量与生物体的衰老程度及逆境伤害程度密切相关。土壤丙二醛（S-MDA）主要来源于植物在逆境胁迫下产生的代谢产物，是评估土壤生态胁迫程度的重要指标。本试剂盒采用硫代巴比妥酸（TBA）比色法测定S-MDA含量：在高温、酸性条件下，MDA与TBA缩合生成红色产物，该产物在532 nm处具有特征吸收峰。为消除可溶性糖等非特异性物质的干扰，同时测定600 nm处的背景吸光值，以ΔOD = OD₅₃₂ – OD₆₀₀计算样品中S-MDA的含量，结合标准曲线即可精准定量。
Malondialdehyde (MDA) is one of the end products of lipid peroxidation in membranes of tissues or organs under aging or stress conditions. Its content is closely related to the degree of aging and stress‑induced damage in organisms. Soil malondialdehyde (S‑MDA) is mainly derived from metabolites produced by plants under stress conditions and serves as an important indicator for assessing the degree of soil ecological stress. This kit employs the thiobarbituric acid (TBA) colorimetric method for the determination of S‑MDA content. Under high‑temperature and acidic conditions, MDA condenses with TBA to form a red product, which exhibits a characteristic absorption peak at 532 nm. To eliminate interference from non‑specific substances such as soluble sugars, the background absorbance at 600 nm is also measured, and the S‑MDA content in the sample is calculated using ΔOD = OD₅₃₂ – OD₆₀₀. Quantitative determination is achieved by comparison with a standard curve.
