Rhamnazin is an O-methylated flavonol, a type of chemical compound. It can be found in Rhamnus petiolaris,[1] a buckthorn plant endemic to Sri Lanka.
Metabolism[edit]
The enzyme 3-methylquercetin 7-O-methyltransferase uses S-adenosyl methionine and isorhamnetin to produce S-adenosyl homocysteine and rhamnazin.
The enzyme 3,7-dimethylquercetin 4'-O-methyltransferase uses S-adenosyl methionine and rhamnazin to produce S-adenosyl homocysteine and ayanin.
