Nontargeted metabolomic analysis of quinoa (Chenopodium quinoa Willd.) using UHPLC-Q-Orbitrap mass spectrometer

Original language description

Quinoa (Chenopodium quinoa Willd.) is a pseudo-cereal from the Chenopodiaceae family firstly domesticated in the mountain region of South America. This highly adaptable and stress-tolerant plant is recognizing increasing popularity in the human diet and because of its superior nutritional properties, quinoa gained the status of a superfood. Moreover, quinoa also contains numerous secondary metabolites that play a significant role in plant protection, many of which are also considered valuable to human health. Five main groups of biologically active metabolites found in quinoa are phenolic acids, flavonoids, terpenoids, steroids, and nitrogen-containing compounds. With the aim of analyzing the metabolomics profile of 5 quinoa varieties, nontargeted analysis on UHPLC-Q-Orbitrap highresolution tandem mass spectrometer was used. Obtained data were processed in Compound discoverer 3.0. As a result, 110 different chemical compounds were identified, from which the largest chemical classes detected in this study were flavonoids (38 compounds), fatty acids (13 compounds), and carboxylic acids (8 compounds). According to available scientific literature [1,2], 95 compounds have not been identified in quinoa before. The most interesting representatives of the flavonoids group were, for example, morin, cirsimaritin, miquelianin, hosludin, cerarvensin, or flemiwallichin D. These findings showed that quinoa possesses a superior variability in secondary metabolites, which deserves further research in this area.
