'''Quercetin''' is a naturally occurring flavonoid found in a wide variety of fruits, vegetables, and grains. It is one of the most abundant antioxidants in the human diet and plays a significant role in helping to protect cells from damage caused by free radicals. | '''Quercetin''' is a naturally occurring flavonoid found in a wide variety of fruits, vegetables, and grains.

Quercetin belongs to the class of polyphenolic compounds known as flavonoids, recognized for their diverse biological activities. It is a pigment that is responsible, in part, for the colors of many fruits, vegetables, and flowers. Structurally, quercetin is characterized by the presence of a 15-carbon skeleton consisting of two phenyl rings and a heterocyclic ring. | Quercetin belongs to the class of polyphenolic compounds known as flavonoids, recognized for their diverse biological activities.

The term "quercetin" is derived from ''quercetum'' (oak forest), reflecting its presence in oak trees. It was first isolated in 1857 by the Austrian chemist Heinrich Hlasiwetz. Since its discovery, quercetin has been the subject of extensive research, with numerous studies exploring its potential health benefits, primarily due to its antioxidant, anti-inflammatory, antiviral, and anticancer properties. | The term "quercetin" is derived from ''quercetum'' (oak forest), reflecting its presence in oak trees.

In plants, quercetin serves as a protective substance, defending against microbial infections and environmental stress. This feature positions quercetin as a xenohormetic compound, implying that it not only protects the plants producing it but also potentially offers health benefits to humans who consume these plants. For humans, it’s predominantly obtained through the consumption of foods such as onions, apples, berries, and teas. Its biological roles in human health are vast, with studies suggesting benefits ranging from anti-aging and anti-inflammatory effects to potential protective roles against various diseases. | In plants, quercetin serves as a protective substance, defending against microbial infections and environmental stress.

: Quercetin’s potent anti-inflammatory properties have led to its investigation for use in chronic inflammatory conditions such as arthritis and cardiovascular diseases. It modulates inflammatory pathways by inhibiting the release of pro-inflammatory cytokines and reducing the activation of inflammatory cells. | : Quercetin’s potent anti-inflammatory properties have led to its investigation for use in chronic inflammatory conditions such as arthritis and cardiovascular diseases.
