Laricitrin is an O-methylated flavonol, a type of flavonoid.

It is found in red grape (absent in white grape)[1] and in Vaccinium uliginosum (bog bilberries).

[2] It is one of the phenolic compounds present in wine.

[3] Laricitrin is formed from myricetin by the action of the enzyme myricetin O-methyltransferase.

[4] It is further methylated by laricitrin 5'-O-methyltransferase into syringetin.
