Phenolic Acids Analysis Service


Phenolic  acids, also known as phenolcarboxylic acids, are types of aromatic acid  compound. They are also a subclass of a larger category of metabolites commonly  referred to as “phenolics”. The term phenolics consists of approximately 8000  naturally occurring compounds, all of which have one common structural feature,  a phenol (an aromatic ring bearing at least one hydroxyl substituent). The  broad category of phenolics can be divided into polyphenols and simple phenols,  based merely on the number of phenol subunits present. Polyphenols containing  at least two phenol substituent groups encompass the flavonoids, and such  compounds containing three or more phenol substituent groups are known as the  tannins (hydrolyzable and non-hydrolyz-able). Two important naturally occurring  types of phenolic acids are hydroxycinnamic acids and hydroxybenzoic acids,  which are derived from non-phenolic molecules of benzoic and cinnamic acid,  respectively.

Phenolic  acids can be found in a number of plant species. Their content in dried fruits  can be very high. Natural phenols in horse grams are typically phenolic acids, that  is 3,4-dihydroxy benzoic, caffeic, vanillic, p-coumaric, sinapinic and syringic  acids. Multiple phenolic acids can be found in human urine. Phenolic acids can also  be found in mushroom. It is a part of the humic substances, which are the main  organic constituents of soil humus.

The  name “phenolic acids” typically describes phenols that possess one carboxylic  acid functional group. Nevertheless, when describing plant metabolites, it  refers to a different group of organic acids. These naturally occurring  phenolic acids possess two distinguishing constitutive carbon frameworks: the  hydroxycinnamic and hydroxybenzoic structures. Although the main skeleton  remains the same, the positions and numbers of the hydroxyl groups on the  aromatic ring produce the variety. In a lot of cases, aldehyde analogues are  grouped in with, and known as, phenolic acids. P-coumaric, caffeic, ferulic,  vanillic, and protocatechuic are acids present in nearly all plant species.

Currently,  a reliable and reproducible method using highly sensitive LC-MS/MS platform for  the rapid identification and quantification of diverse phenolic acids in  different sample types has been developed by the experienced biological scientists  at Creative Proteomics, which can meet the needs of academic and industrial  study in your lab.
