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.

Well, that’s interesting to know that Psilotum nudum are known as whisk ferns. Psilotum nudum is the commoner species of the two. While the P. flaccidum is a rare species and is found in the tropical islands. Both the species are usually epiphytic in habit and grow upon tree ferns. These species may also be terrestrial and grow in humus or in the crevices of the rocks.
