Abstract
Quercetin is a major flavonoid in plant foods and potentially has beneficial effects on disease prevention. The present work demonstrated that quercetin was transported into the lymph after being metabolized in the gastrointestinal mucosa of rats. Glucuronide/sulfate and methylated conjugates of quercetin appeared in the lymph, but not quercetin aglycone. The highest lymphatic concentration was found at as rapid as 30 min after administration, suggesting gastric absorption, whereas the mucosal glucuronidation activity was significantly higher in the duodenum and jejunum than in the stomach. This is the first report to show the lymphatic flavonoid transport pathway from the gastrointestinal tract.
