Antioxidant Change in Biosynthesis from Naringenin Chalcone to Flavonoid Apingenin

Naringenin chalcone (NAC) can undergo biosynthesis to convert into dihydroflavonoid naringenin and then to flavonoid apigenin. To explore the antioxidant change during this biosynthesis, the three were comparatively analyzed using several methods. Ultra‐performance liquid chromatography coupled with electrospray ionization quadrupole time‐of‐flight tandem mass spectrometry analysis gave a dimer MS peak and an adduct MS peak when each of them...
