Ayanin is an O-methylated flavonol, a type of flavonoid. It is the 3,7,4'-tri-O-methylation of quercetin.

It can be found in Croton schiedeanus. It can also be synthetized.[1]

Biosynthesis

The enzyme 3,7-dimethylquercetin 4'-O-methyltransferase uses S-adenosyl methionine and 5,3',4'-trihydroxy-3,7-dimethoxyflavone (rhamnazin) to produce S-adenosylhomocysteine and 5,3'-dihydroxy-3,7,4'-trimethoxyflavone (ayanin).
