Fustin, sometimes called "dihydrofisetin", is a flavanonol, a type of flavonoid. It can be found in young fustic (Cotinus coggygria)[1] and in the lacquer tree (Toxicodendron vernicifluum).[2]

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

Unlike fisetin, fustin has no double bond in the C-ring. This makes fustin a flavan, with two stereocenters and four stereoisomers.
