Chemical Information
FooDB NameSyringic acid
DescriptionPresent in various plants free and combined, e.g. principal phenolic constituent of soyabean meal (Glycine max) Syringic acid is a phenol present in some distilled alcohol beverages. It is also a product of microbial (gut) metabolism of anthocyanins and other polyphenols that have been consumed (in fruits and alcoholic beverages - PMID: 18767860). Research suggests that phenolics from wine may play a positive role against oxidation of low-density lipoprotein (LDL), which is a key step in the development of atherosclerosis. Syringic acid is correlated with high antioxidant activity and inhibition of LDL oxidation. (PMID 15545043). Syringic acid is found in many foods, some of which are common pea, mung bean, rosemary, and dill.
