Syringetin is anO-methylated flavonol, a type of flavonoid. It is found inred grape (absent in white grape),[1] inLysimachia congestiflora[2] and inVaccinium uliginosum (bog bilberries).[3] It is one of thephenolic compounds present in wine.[4]
It induces human osteoblast differentiation throughbone morphogenetic protein-2/extracellular signal-regulated kinase 1/2 pathway.[4]
Syringetin is formed fromlaricitrin by the action of the enzyme laricitrin 5′-O-methyltransferase[1][5] (myricetinO-methyltransferase).[6]
