quercetin productQuercetin, a plant flavonol from the flavonoid group of polyphenols, is found in many fruits, vegetables, leaves, and grains; red onions and kale are common foods containing appreciable content of quercetin. It has a bitter flavor and is used as an ingredient in dietary supplements, beverages, and foods.


Quercetin is one of the most abundant dietary flavonoids,with an average daily consumption of 25–50 milligrams.In red onions, higher concentrations of quercetin occur in the outermost rings and in the part closest to the root, the latter being the part of the plant with the highest concentration.One study found that organically grown tomatoes had 79% more quercetin than non-organically grown fruit.Quercetin is present in various kinds of honey from different plant sources.


Quercetin (C15H10O7) is an aglycone, lacking an attached sugar. It is a brilliant citron yellow needle crystal and entirely insoluble in cold water, poorly soluble in hot water, but quite soluble in alcohol and lipids. A quercetin glycoside is formed by attaching a glycosyl group (a sugar such as glucose, rhamnose, or rutinose) as a replacement for one of the OH groups (commonly at position 3). The attached glycosyl group can change the solubility, absorption, and in vivo effects. As a general rule of thumb, the presence of a glycosyl group (quercetin glycoside) results in increased water solubility compared to quercetin aglycone .


A quercetin glycoside is unique by the attached glycosyl group. Generally, the term quercetin should be used to describe the aglycone only; however, the name is occasionally used to refer to quercetin-type molecules, including its glycosides in research and the supplement industry.
