Syringic acid is a naturally occurring O-methylated trihydroxybenzoic acid, a type of chemical compound.
Syringic acid can be found in Ardisia elliptica.
Presence in food
It is also present in wine. Its presence in the ancient Egyptian drink shedeh could confirm it was made out of grape, as syringic acid is released by the breakdown of the compound malvidin, also found in red wine. It is also found in vinegar.
Syringic acid can be enzymatically polymerised. Laccase and peroxidase induced the polymerization of syringic acid to give a poly(1,4-phenylene oxide) bearing a carboxylic acid at one end and a phenolic hydroxyl group at the other.
