Petunidin (Pt) is an O-methylated anthocyanidin. It is a natural organic compound and a particular type of anthocyanidin. It is a dark-red or purple water-soluble pigment found in many redberries including chokeberries (Aronia sp), Saskatoon berries (Amelanchier alnifolia) or different species of grape (for instance Vitis vinifera, or muscadine, Vitis rotundifolia), and also part of the pigments responsible for the petal colors in many flowers. The name of the molecule itself is derived from the word Petunia.
Petunidin could form in the exocarp of fruits from delphinidin, with an anthocyanin flavonoid O-methyltransferase (Catechol-O-methyl transferase) catalyzing the B-ring methylation and S-Adenosyl-L-methyl-3H methionine being the methyl group donor.
