Analysis of metabonomic changes of hepatic vein plasma after oral administration of quercetin in rats / 肠外与肠内营养

ABSTRACT

Objective: To investigate the effects of quercetin on hepatic vein metabolic profiles in rats. Methods: Male Wistar rats were administrated orally with 40 mg/kg quercetin. Hepatic vein plasma was collected at 0 h, 0.5 h, 1 h, 2 h and 4 h respectively after administration and analyzed by 1H NMR. Results: The identifiable biochemical effects associated with quercetin dosing included decreased plasma concentration of glucose and increased plasma concentration of succinate,β-hydroxybutyrate and pyruvate. Conclusion: Quercetin changes hepatic metabolism in rats, manifested mainly as increased glucose catabolism and production of ketone bodies.
