| Outline of Final Research Achievements |
Flavonoids are rich in fruits and vegetables. Flabonoids after absorption into the body are metabolized and mainly excreted via bile which abundantly contains various lipids. Howevwe, influence of biliary flavonoid metabolites on the biliary lipid profiles are not well-studied. In this study, we investigated the influence of flavonoids on biliary composition in rats and mice. In rats given one-shot administration of anthocyanin, biliary triglyceride (TG) increased and hepatic TG content subsequently decreased, whereas in rats given quercetin, biliary lipids except but TG were totally reduced. A black soybean seed coat extract, which abundantly contains anthocyanin, lowered excretion of cholesterol into bile and tended to prevent gallstone formation.
