Common NameSyringic acid
DescriptionSyringic acid, also known as syringate or cedar acid, belongs to the class of organic compounds known as gallic acid and derivatives. Gallic acid and derivatives are compounds containing a 3,4,5-trihydroxybenzoic acid moiety. Outside of the human body, Syringic acid is found, on average, in the highest concentration within a few different foods, such as common walnuts, swiss chards, and olives and in a lower concentration in apples, tarragons, and peanuts. Syringic acid has also been detected, but not quantified in several different foods, such as sweet marjorams, silver lindens, bulgurs, annual wild rices, and barley. This could make syringic acid a potential biomarker for the consumption of these foods. Syringic acid is correlated with high antioxidant activity and inhibition of LDL oxidation. 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 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 ). Syringic acid is also a microbial metabolite that can be found in Bifidobacterium (PMID: 24958563 ).
