A new type of flavonoid was isolated from an adzuki bean-water extract by various chromatographic techniques. The chemical structure was determined by ultraviolet-visible (UV-Vis) spectroscopy, mass spectrometry (MS), and various nuclear magnetic resonance (NMR) experiments, and it was found to be unique in that the xanthylium skeleton was present in this molecule.
