Fustin
Fustin, sometimes called "dihydrofisetin", is a flavanonol, a type of flavonoid. It can be found in young fustic and in the lacquer tree.
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.
