General description

Quercetin is an important flavonoid present in most of the vegetables including onion. Quercetin 3-glucuronide is one of the polyphenol metabolites, that is found to be localized to the brain.

Biochem/physiol Actions

Natural compound isolated from onions. Belongs to the class of organic compounds known as flavanoid-3-o-glycosides. Quercetin possesses free radical scavenging activity, due to the presence of phenolic hydroxyl groups present at the B-ring and position 3. The glycosidic form of quercetin is metabolized to its conjugates (glucuronide or sulfate) for absorption in the intestine.
