Ayanin is an O-methylated flavonol, a type of flavonoid. It is the 3,7,4'-tri-O-methylated derivative of quercetin.
It can be found in Croton schiedeanus. It can also be synthesized.[1]
Biosynthesis[edit]
The enzyme 3,7-dimethylquercetin 4'-O-methyltransferase uses S-adenosyl methionine and rhamnazin to produce S-adenosylhomocysteine and ayanin.
