Relative percent glucuronide product formation for the reactions of UGT enzymes with: (A) 7-hydroxyflavanone, (B) 3'-hydroxyflavanone, (C) 4'-hydroxyflavanone, (D) 2'-hydroxychalcone. A * indicates that less than 5% of the flavonoid aglycone remains. Glucuronide product distributions were estimated using LC-UV chromatograms by dividing the glucuronide peak area by the sum of the peak areas for the unreacted aglycone and glucuronide product for a given reaction. Relative standard deviations were generally less than 10% for replicate measurements.
