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 Myricetin is a member of the flavonoid class of polyphenolic compounds, with antioxidant properties. Common dietary sources include vegetables (including tomatoes), fruits (including oranges), nuts, berries, tea, and red wine. Myricetin is stru ...

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