Syringic acid is a naturally occurring O-methylated phenolic acid that can be enzymatically degraded by some bacteria as a source of methane or methanol. It is also a component of phenolic extracts from various plants that have antioxidant and prooxidant activities. Syringic acid has been shown to inhibit aldose reductase (IC50 = 213 µg/ml), proteasome activity, and cancer cell proliferation. Phenolic extracts containing syringic acid have been shown to inhibit α-amylase and α-glucosidase activities and reduce lipid peroxidation in vitro.
