Chemical Profile and Chemometric Analysis of Genetically Modified Soybeans Produced in the Triângulo Mineiro Region (MG), Brazil

Soy production in Brazil is an important factor for the agro-industrial, economic, and social development of country. The expansion soy Brazilian territory mainly due to incorporation new genetic characteristics into cultivars that granted resistance Cerrado conditions herbicides. Currently, result genetically modified cultivars. Studies regarding chemical composition soybeans show qualitative quantitative variations can occur, depending on region production. This work aimed investigate produced different cities Triângulo Mineiro region/MG, (Harvest 2017/2018) stored three warehouses located city Uberaba/MG. grain analysis was made by liquid chromatography coupled electrospray ionization mass spectrometry (LC-MS-ESI). classes metabolites identified from methanolic extraction were organic acids, phenolic compounds, flavonoids, sugars, amino dipeptides, nitrogenous bases, nucleosides, sphingolipids, fatty acids. isoflavones genistein, daidzein, glycitein, genistin, acetyldaidzin, acetylgenistin warehouses. flavonoid eriodictyol-O-hexoside also found. Principal Component Analysis (PCA) spectrum data obtained direct injection negative positive modes evidenced well-defined separation groups, indicating there variance among samples each warehouse. 1 3 showed greater similarity Hierarchical Cluster (HCA) mode, while 2 presented similarity.
