Abstract:

The chirality of flavonoids has been overlooked in the majority of pharmacokinetic studies of homoeriodictyol, isosakuranetin, and taxifolin. The stereospecific pharmacokinetic disposition of these xenobiotics in male Sprague-Dawley rats is described for the first time. Validated HPLC methods were used to analyze serum and urine samples of rats following intravenous administration of each flavonoid via jugular vein cannulation and to determine their content in selected fruits. The characterization and interpretation of the pharmacokinetic disposition profiles of homoeriodictyol, isosakuranetin, and taxifolin are described. A discrepancy exists between half-lives in serum and urine which may be attributed to low assay sensitivity in serum for the three compounds; thus, a more accurate estimation of the pharmacokinetic parameters was obtained from urine. The pharmacokinetics of homoeriodictyol, isosakuranetin, and taxifolin revealed distribution, metabolism, and elimination that were dependent on the stereochemistry of the stereoisomers. The (-)-(S)-enantiomers of homoeriodictyol and isosakuranetin and the (+)-(2S; 3R)-stereoisomer of taxifolin were predominant in lemon, grapefruit, and tomato. These findings were achieved using chiral methods of analysis; the utility and necessity of developing chiral methods of analysis for chiral xenobiotics are discussed.
