The relative contribution of the small and large intestine to the absorption and metabolism of rutin in man.
Tomato juice containing rutin (quercetin-3-rutinoside) was ingested by healthy volunteers and ileostomists. Blood and urine collected over 24 h were analysed by HPLC with photodiode array (PDA) and tandem mass spectrometric detection. Low concentrations of isorhamnetin-3-glucuronide (Cmax = 4.3 +/- 1.5 nmoles/l) and quercetin-3-glucuronide (Cmax = 12 +/- 2 nmoles/l) were detected in plasma of healthy subjects. Metabolites appeared in blood after 4 h indicating absorption from the large intestine. Nine metabolites of rutin were detected in urine but with considerable variation in total amount (40 +/- 1-4981 +/- 115 nmoles over 24 h). No metabolites were detected in plasma or urine of ileostomists and 86 +/- 3% of the ingested rutin was recovered in ileal fluid. In subjects with an intact large intestine, but not ileostomists, rutin was catabolised with the appearance of 3,4-dihydroxyphenylacetic acid, 3-methoxy-4-hydroxyphenylacetic acid and 3-hydroxyphenylacetic acid in urine accounting for 22% of rutin intake.[1]References
