Fisetin (7,3′,4′-flavon-3-ol) is a plant flavonol from the flavonoid group of polyphenols.[1] It can be found in many plants, where it serves as a yellow/ochre colouring agent. It is also found in many fruits and vegetables, such as strawberries, apples, persimmons, onions and cucumbers.[2] Its chemical formula was first described by Austrian chemist Josef Herzig in 1891.[3]
The biological activity of fisetin has been studied in many laboratory assays; like other polyphenols it has many activities.
