phenolic acid
Phenolic acids or phenolcarboxylic acids are types of aromatic acid compound. Included in that class are substances containing a phenolic ring and an organic carboxylic acid function (C6-C1 skeleton).
There are several categories of phenolic acids including:
*Monohydroxybenzoic acids: salicylic acid, 3-Hydroxybenzoic acid, 4-Hydroxybenzoic acid
*
*Some esters of this group include paraben, methyl paraben, propyl paraben
*Dihydroxybenzoic acids: vanillin, vanillic acid, gentisic acid, protocatechuic acid
*Trihydroxybenzoic acids: gallic acid, ellagic acid, syringic acid, eudesmic acid, phloroglucinol carboxylic acid
*
*This type of phenolic acids (especially gallic acid, ellagic acid) is a component of hydrolysable tannins.

Phenolic acids can be found in many plant species. Their content in dried fruits can be high.
Natural phenols in horse grams (''Macrotyloma uniflorum'') are mostly phenolic acids, namely 3,4-dihydroxy benzoic, ''p''-hydroxy benzoic, vanillic, caffeic, ''p''-coumaric, ferulic, syringic and sinapinic acids.〔Identification and quantification of phenolic acids in Macrotyloma uniflorum by reversed phase HPLC.

Phenolic acids can be found in mushroom Basidiomycetes species. It is also a part of the humic substances, which are the major organic constituents of soil humus.
