木质素是第二丰富的天然聚合物，是传统化石燃料的有前途的替代能源。在这项研究中，我们研究了木质素化合物在人工紫外光条件下在分子水平上的转化。在石油经济学领域中，已经针对原油研究了太阳暴露后自然界中的这种光诱导的组成分布的变化。我们采用了类似的高分辨率质谱实验策略，木质素，并展示了各种数据处理方法，以揭示两个样品集，一个本地控制前和一个样品后，光照射，使用傅里叶变换离子回旋共振质谱的极其复杂的数据集之间的特征差异。
Lignin is the second most abundant natural polymer and a promising alternative energy source for conventional fossil fuels. In this study, we investigated transformations of lignin compounds under artificial UV light conditions at the molecular level. Such light-induced changes of composition profiles in nature after sun exposure have been studied for crude oil in the petroleomics field. We applied a similar high resolution mass spectrometry experimental strategy to lignin and demonstrated various data processing methods to reveal the characteristic differences between the extremely complex data sets of two sample sets, one native control before and one sample after photo-irradiation, using Fourier transform ion cyclotron resonance-mass spectrometry.
