Syringic acid is a potential antioxidant used in traditional Chinese medicine and is an emerging nutraceutical. It has potential anti-angiogenic, anti-glycating, anti-hyperglycaemic,antimicrobial, fungitoxicity, neuroprotective, antimitogenic, chemo-sensitizing, anti-obesity, anti-inflammatory, anti-steatotic, and memory-enhancing properties. Syringic acid can ameliorate L-arginine methyl ester-induced hypertension by reducing oxidative stress, and can reduce the pancreatic damage induced by alloxan and stimulated β-cell regeneration in diabetic rats. Syringic acid can suppress hepatic fibrosis in chronic liver injury, it inhibits the activation of cultured hepatic stellate cells. Syringic acid is a dimethoxybenzene that is 3,5-dimethyl ether derivative of gallic acid. It has a role as a plant metabolite. It is a member of benzoic acids, a member of phenols and a dimethoxybenzene. It is functionally related to a gallic acid. It is a conjugate acid of a syringate.
