Isoflavones are contained in several products made of soybeans. They are known to be functional compounds with antioxidant properties and for their metabolites for having estrogenic properties. Soybean isoflavones contain 15 types of isoflavones: 3 types of isoflavones (daidzein, glycitein and genistein) called Aglycone (non-glycoside),
3 types of glycosides (daidzin, glycitin, genistin), 3 types of acetylated glycosides, 3 types of malonylated glycosides and 3 types of succinylated isoflavone glycosides.
In this note InertSustainSwift C18 column was used to analyze 12 types of soybean isoflavones (the 3 types of succinylated isoflavone glycosides are not been considered in this analysis).
