Chemical Information
FooDB NameGentisic acid
DescriptionGentisic acid is a dihydroxybenzoic acid. It is a crystalline powder that forms monoclinic prism in water solution. Gentisic acid is an active metabolite of salicylic acid degradation. There is an increasing amount of evidence indicating that gentisic acid has a broad spectrum of biological activity, such as anti-inflammatory, antirheumatic and antioxidant properties. Gentisic acid is also a byproduct of tyrosine and benzoate metabolism. [HMDB]. Gentisic acid is found in many foods, some of which are common sage, common grape, nutmeg, and dill.
