Corvitin is a soluble form of quercetin (QUE) and its effects are based on the ability to inhibit the activity of 5-lipoxygenase and to block the formation of leukotrienes. Corvitin increases bloodflow in the stomach­, pancreas and liver, but its influence on the excretory liver function has not been studied. We investigated the effect of corvitin (2.5, 5, 10 mg/kg intraportally) on bile formation, determined the biliary content of total, free and conjugated bile acids (BAs). Free and conjugated BAs were separated by thin layer chromatography method. It was shown that corvitin increased the content of total BAs in the bile of rats in all tested groups. At a dose of 2.5 mg/kg flavonoid did not сhange free BAs secretion, but while elevated the content of conjugated BAs. Both free and conjugated BAs secretion was increased in rats treated with corvitin at a dose of 5 mg/kg. Increasing of corvitin dose to 10 mg/kg resulted in enhanced secretion of free BAs. Consequently, inhibition of leukotrienes synthesis by corvitin is followed by modulation of total, free and conjugated BAs  formation and secretion into the bile.
