Fustin

Fustin, sometimes called 'dihydrofisetin', is a flavanonol, a type of flavonoid. It can be found in young fustic (Cotinus coggygria) and in the lacquer tree (Toxicodendron vernicifluum). Fustin, sometimes called 'dihydrofisetin', is a flavanonol, a type of flavonoid. It can be found in young fustic (Cotinus coggygria) and in the lacquer tree (Toxicodendron vernicifluum). Fustin shows protective effects on 6-hydroxydopamine-induced neuronal cell death. Unlike fisetin, fustin has no double bond in the C-ring. This makes fustin a flavan, with two stereocenters and four stereoisomers.
