Syringic acid, the 3,5-dimethyl ether derivative of gallic acid, is a phenolic compound often found in fruits and vegetables which is synthesized via the shikimic acid pathway in plants. Syringic acid, reviewed by Cheemanapalli and colleagues in 2018, has a broad bioprofile, possessing antioxidant, antimicrobial, anti​inflammatory, antiendotoxic, neuro- and hepatoprotective activities.  It is an effective free radical scavenger and alleviates the oxidative stress markers. Syringic acid application to plants increases lignin deposition in interfascicular fibers and attenuates cesium-induced growth defects in Arabidopsis.
