Description | Gentisic acid, also known as gentisate or 2,5-dioxybenzoate, belongs to the class of organic compounds known as hydroxybenzoic acid derivatives. Hydroxybenzoic acid derivatives are compounds containing a hydroxybenzoic acid (or a derivative), which is a benzene ring bearing a carboxyl and a hydroxyl groups. Gentisic acid is also classified as a dihydroxybenzoic acid. It is a derivative of benzoic acid and a minor (1%) product of the metabolic break down of aspirin, which is excreted by the kidneys. Gentisic acid is found in essentially all organisms ranging from bacteria to fungi to plants to animals. Gentisic acid has been associated with a number of useful effects on human health and exhibits anti-inflammatory, antigenotoxic, hepatoprotective, neuroprotective, antimicrobial, and especially antioxidant activities (PMID: 31825145 ). It is widely distributed in plants as a secondary plant product such as Gentiana spp., Citrus spp., Vitis vinifera, Pterocarpus santalinus, Helianthus tuberosus, Hibiscus rosa-sinensis, Olea europaea, and Sesamum indicum and in fruits such as avocados, batoko plum, kiwi fruits, apple, bitter melon, black berries, pears, and some mushrooms (PMID: 31825145 ). Gentisic acid is found in higher concentrations in a number of foods such as tarragons, common thymes, and common sages and in a lower concentration in grape wines, rosemaries, and sweet marjorams. Gentisic acid has also been shown to act as a pathogen-inducible signal for the activation of plant defenses in tomato plants and cucumbers (PMID: 16321412 ; Https://Doi.Org/10.1094/MPMI.1999.12.3.227). |
