Laricitrin is an O-methylated flavonol, a type of flavonoid. It is found in red grape (absent in white grape) and in Vaccinium uliginosum (bog bilberries). It is one of the phenolic compounds present in wine.

Metabolism

Laricitrin is formed from myricetin by the action of the enzyme myricetin O-methyltransferase. It is further methylated by laricitrin 5'-O-methyltransferase into syringetin.
