Gossypetin
Gossypetin, also known as 3,5,7,8,3',4'-hexahydroxyflavone, is a flavonol, a type of flavonoid. It has been isolated from the flowers and the calyx of Hibiscus sabdariffa (roselle) and exhibits a strong antibacterial activity.[1][2] The compound has also been found to act as an antagonist of TrkB.[3] Recently it was shown that gossypetin has radioprotective activity.

The enzyme 8-hydroxyquercetin 8-O-methyltransferase uses S-adenosyl methionine and gossypetin to produce S-adenosylhomocysteine and 3,5,7,3',4'-pentahydroxy-8-methoxyflavone.
