Metabolomics analysis reveals the accumulation patterns of flavonoids and phenolic acids in quinoa (Chenopodium quinoa Willd.) grains of different colors

ABSTRACT: Highlights • A total of 689 metabolites were identified in the grains of three quinoa varieties.• 102 flavonoids and 97 phenolic acids were identified in quinoa grains.• Most differential metabolites were significantly more abundant in colored quinoa grains than in white grains.• Flavonoids and phenolic acids could act as co-pigments of betanin in quinoa grains. Quinoa grains are gaining increasing popularity owing to their high nutritional merits. However, only limited information is available on the metabolic profiles of quinoa grains. In this study, we determined the metabolic profiles of black, red, and white quinoa grains via an ultraperformance liquid chromatography–electrospray ionization–tandem mass spectrometry (UPLC–ESI–MS/MS)-based metabolomics. A total of 689 metabolites were i
