Phenolic acids or phenolcarboxylic acids are phenolic compounds and types of aromatic acid compounds. Included in that class are substances containing a phenolic ring and an organic carboxylic acid function (C6-C1 skeleton). Two important naturally occurring types of phenolic acids are hydroxybenzoic acids and hydroxycinnamic acids, which are derived from non-phenolic molecules of benzoic and cinnamic acid, respectively. [1]
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.[ citation needed]
Phenolic acids can be found in several mushroom-forming species of basidiomycetes. [2] It is also a part of the humic substances, which are the major organic constituents of soil humus.
Many phenolic acids can be found in human urine. [3]
Immobilized Candida antarctica lipase can be used to catalyze the direct acetylation of flavonoids with phenolic acids. [4]
