Here we report a simple and fast method for wine fingerprinting based on direct matrix-assisted laser desorption/ionization (MALDI) mass spectrometry analysis of different red wine samples, useful for batch-to-batch analysis and for the detection of key compounds even in trace amounts which may vary from vintage to vintage, and from one treatment to another one. A series of 20 samples from different wines were subjected to MALDI mass spectrometry. We found that 2,5-dihydroxybenzoic acid is far superior with respect to all the matrices tested To the best of our knowledge this is the first application of an effective wine profiling not limited to detection of anthocyanins. More than 80 molecular species were detected. Moreover, qualitative and quantitative differences were observed, owing to the nature and relative abundance of different chemical compounds among the wines.
在此，我们报告一种基于直接基质辅助激光解吸/电离（MALDI）质谱分析不同红酒样品的简单快速的葡萄酒指纹图谱方法，该方法可用于批次间分析，甚至能检测出不同年份以及不同处理方式下含量可能有所变化的痕量关键化合物。对来自不同葡萄酒的一系列20个样品进行了MALDI质谱分析。我们发现，2,5 - 二羟基苯甲酸在所有测试的基质中表现优异。据我们所知，这是首次将有效的葡萄酒分析方法应用于不限于花青素检测的情况。检测到了80多种分子种类。此外，由于不同葡萄酒中不同化合物的性质和相对丰度，观察到了定性和定量的差异。
