植物特化代謝物の構造解析に向けた電子励起解離法によるMS/MS解析基盤の構築
The comprehensive profiling of plant specialized metabolites (natural products) by liquid chromatography coupled with tandem mass spectrometry is an outstanding issue in metabolomics due to the lack of authentic standard compounds. Therefore, we evaluated the tandem mass spectra (MS/MS) of electron activated dissociation (EAD) to elucidate the natural product structures. The EAD-MS/MS spectra of 716 standard compounds were obtained, and the spectral entropy distribution was investigated. The spectra were further evaluated for predicting metabolite classes in molecular spectrum networking, where we found that more informative product ions were obtained in EAD-MS/MS to elucidate the plant metabolites including alkaloids.
