QUERCETIN DIHYDRATE(RG) Usage And Synthesis

Uses

Quercetin 3,4''-Diglucoside is a flavonoid that has shown to be the antioxidative phenolic constituent of skins of onions.

Definition

ChEBI: Quercetin 3,4'-di-O-beta-D-glucoside is a quercetin O-glucoside that is quercetin with two beta-D-glucosyl residues attached at positions 3 and 4'. It has a role as a plant metabolite, a radical scavenger and a cardioprotective agent. It is a beta-D-glucoside, a monosaccharide derivative, a polyphenol, a quercetin O-glucoside and a trihydroxyflavone.

Biological Activity

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.', 'Natural compound isolated from onions. Belongs to the class of organic compounds known as flavanoid-3-o-glycosides.
