Fustin is a flavanonol, a type of flavonoid. It can be found in young fustic (Cotinus coggygria)^[1] and in the lacquer tree^[2] (Toxicodendron vernicifluum, aka Rhus verniciflua).

Fustin shows protective effects on 6-hydroxydopamine-induced neuronal cell death^[2].

Fustin is also known as "dihydrofisetin"; see Fisetin.

Fustin possesses stereoisomers : (-)-Fustin and (+)-Fustin.
