    Description

    Miquelianin (quercetin 3-O-glucuronide) is a flavonol glucuronide, a type of phenolic compound present in wine, in species of St John's wort, like Hypericum hirsutum, in Nelumbo nucifera (Indian lotus) or in green beans.
    It is also a rat plasma quercetin metabolite. It shows an antioxidant effect in human plasma. In vitro studies indicate that miquelianin is able to reach the central nervous system from the small intestine.
