Quercetin is ubiquitously distributed in plant foods. This antioxidative polyphenol is mostly
converted to conjugated metabolites in the body. Parkinson disease (PD) has been …

To assess the efficacy of conjugated quercetin metabolites as attenuators for oxidative stress
in the central nervous system, we measured the 13-hydroperoxyoctadecadienoic acid (13 …

In the present study, we examined the ability of a flavonoid quercetin to prevent 6-
hydroxydopamine (6-OHDA)-induced oxygen radical formation and cytotoxicity in vitro and …

There is increasing evidence that free radicals induced oxidative stress is a major causative
agent in the pathogenesis of neurodegenerative diseases, particularly Parkinson's disease …

Flavonoids are reported to be powerful antioxidants in cell free systems. They naturally
occur as glycosides rather than as aglycon. In this study the ability of the flavonoid quercetin …

An increasing large body of research on Parkinson's disease (PD) has focused on the
understanding of the mechanisms behind the potential neuro protection offered by …

The potential beneficial effect of dietary quercetin (3, 3′, 4′, 5, 7-pentahydroxyflavone)
has attracted much attention in relation to the prevention of cardiovascular disease. It is …

Since flavonols are antioxidant agents, they could in principle, beneficially affect
neurodegenerative diseases where reactive oxygen species are involved. Quercetin …

Although the cause of dopaminergic cell death in Parkinson's disease (PD) remains
unknown, oxidative stress has been strongly implicated. Because of their ability to combat …

Quercetin glycosides, rutin and isoquercitrin, are potent antioxidants that have been found to
possess neuroprotective effect in diseases like Parkinson's and Alzheimer's disease. In the …
