Note: Flavonoids are phenolic substances isolated from a variety of plants and fruits. They are low molecular weight compounds and in plants they are usually bound to sugar molecules as O-glycosides. Flavonoids are present in foods and beverages of plant origin, such as fruits, vegetables, tea, wine etc. They can be divided into fourteen classes, including flavonols, flavones, anthocyanins, isoflavonoids, and flavanones. They have been shown to have anti-inflammatory, anti-allergic, anti-carcinogenic, antihypertensive and anti-arthritic, and free radical scavenging properties.
