Ultrafast COSY NMR spectra (aromatic region) (117) recorded in real time in the course of a HPLC-NMR run on a mixture of naringin (blue), epicatechin (red) and naringenin (green), 10 mg/mL each, dissolved in acetonitrile/water/D2O 45:27.5:27.5. The spectra were recorded with double solvent presaturation, at 298 K on a 600 MHz Bruker Avance III spectrometer equipped with a cryogenic probe, including a cryofit accessory with an active cell volume of 60 µL.
