Non-targeted metabolomics of quinoa seed filling period based on liquid chromatography-mass spectrometry.

摘要: Abstract Quinoa (Chenopodium quinoa Willd.), an herb belonging to the amaranth family, is rich in minerals, amino acids, vitamins, proteins, and flavonoids. Its grain, compared with other major grains, has unique nutritional value tremendous applications. This study used four independently bred high-generation lines (seed colors) of as materials further understand metabolic differences filling periods varieties. Additionally, non-targeted metabolome seeds 35 42 days after flowering, respectively, were studied via liquid chromatography-mass spectrometry. The two yellow, white, black, red grains resulted significant metabolites, particularly L-methionine, S-adenosyl-L-homocysteine, S-adenosyl-L-methionine, pyruvate, fumarate, oxaloacetate. Soluble sugar, acid, fatty acid contents increased flowering. There between sugar phosphates (L-fucose, D-mannose-6-phosphate, xylulose-5-phosphate, sedoheptulose-7-phosphate), (alanine), organic compounds (kynurenate, tryptamine, serotonin, bilirubin) among relative difference metabolites was largest when yellow grain varieties smallest black compare. results this provide a basis for reproduction identification new varieties, well screening potential quality control target genes by combining genomics transcriptomics.
