*Red clover samples were collected from five different locations across University of Tennessee research centers.
†BG = biochanin A glucoside (sissotrin), FG = formononetin glucoside (ononin), GG = genistein glucoside (genistin), DG = daidzein glucoside (daidzin), BMG = biochanin A malonyl glucoside, and FMG = formononetin malonyl glucoside.
‡Corrected for hydrolysis.
||Measured in μg × 600 mg tablet−1.
