The aim of this study was to evaluate the content of different forms of isoflavones of BRS 284 soybean components and the effect of germination time in the cotyledons, radicle, and hypocotyl. Seeds were germinated until 168 h at 35 °C and collected each 24 h. The isoflavone content was determined by ultraperformance liquid chromatography, and the data were subjected to regression analysis. In cotyledons, germination time had a quadratic effect on daidzin and genistin contents and a linear effect on malonyldaidzin and malonylgenistin contents. In radicles, germination time had a quadratic effect on daidzin, glycitin, malonylgenistin, and malonylglycitin contents in addition to a linear effect on malonyldaidzin content. In hypocotyls, germination time showed a cubic effect on daidzin and genistin contents, a quadratic effect on malonyldaidzin, malonylgenistin, and malonylglycitin contents, and a linear effect on genistein content; glycitin, daidzein and glycitein were detected in a few germination times.
