flavonoidglükosiide

Flavonoid glycosides are a class of naturally occurring compounds found in plants. They are a type of flavonoid, which are a diverse group of polyphenolic secondary metabolites. The "glycoside" part of the name indicates that these compounds are formed by a flavonoid molecule linked to one or more sugar molecules, typically glucose or rhamnose. This linkage occurs through a glycosidic bond.

The presence of the sugar moiety significantly influences the physical and chemical properties of the flavonoid. Glycosides are generally more water-soluble than their aglycone (non-sugar) counterparts. This increased solubility affects their absorption, distribution, metabolism, and excretion in biological systems.

Flavonoid glycosides are widely distributed in the plant kingdom and are found in various edible fruits, vegetables, grains, and beverages such as tea and wine. Examples include quercetin glycosides like rutin and quercitrin, and anthocyanin glycosides which are responsible for the red, blue, and purple colors in many plants.

These compounds have garnered interest due to their potential biological activities, including antioxidant, anti-inflammatory, and cardioprotective effects. The specific activity can vary depending on the particular flavonoid glycoside structure and the plant source. Research continues to explore the health benefits and mechanisms of action associated with these plant-derived compounds.
