Metabolic profiling of flavonoids in Lotus japonicus using liquid chromatography Fourier transform ion cyclotron resonance mass spectrometry

A comprehensive flavonoid analysis using LC-FTICR/MS established the presence of 61 flavonoid metabolites including gossypetin and isorhamnetin derivatives in Lotus japonicus accessions MG-20 and B-129. Flavonoid profiling demonstrated that anthocyanins and flavonol glycosides accumulated in a tissue- and development-dependent manner.
