MassBank Human: The annotated human metabolome

Mass spectrometry-based metabolomics is essential for deciphering human metabolic functions and metabolite dark matter. However, the dark matter of the human metabolome is intricately hidden. Therefore, we developed MassBank Human, a curated library that distills 36,512,540 MS2 spectra from 76 public human datasets int...

Stable Isotope-Assisted Computational Mass Spectrometry Reveals Root-Specific Homopipecolic Acid-Containing Flavonoids in Glycyrrhiza Species

The carbon number was determined, followed by the molecular formula and substructure prediction in combination with MS/MS similarity-based molecular networking, and five previously unreported homopipecolic acid-conjugated flavonoids in the roots of G. uralensis and G. glabra were discovered.
