General description

Sinapic acid is one of the 4 most common hydroxycinnamic acids. It is widespread in the plant kingdom (vegetables, fruits, oilseed crops, cereal grains and medicinal plants, and some spices). It is mostly found in the form of esters, but may exist in the free form too.[04]

Biochem/physiol Actions

On removal of amino group from phenylalanine, catalysing with enzyme phenylalanine ammonia-lyase forms cinnamic acid. The precursor of hydroxycinnamates is produced after hydroxylation of benzene ring. One of the precursors produced is sinapic acid. Sinapic acid exhibits antimicrobial, antioxidant, anticancer, anti-inflammatory, and anti-anxiety activity. Sinapine (sinapoyl choline) has been acknowledged as an acetylcholinesterase inhibitor, making it therapeutically applicable in treatment of various diseases. 4-Vinylsyringol (a decarboxylation product of sinapic acid) is a potent antimutagenic and antioxidative agent, involved in suppressing the induction of inflammatory cytokines and carcinogenesis. Owing to their anti-oxidative activity, these compounds have been considered to be potentially employed in the pharmaceutical industry, cosmetics and food processing.[05][09]
Sinapic acid was suitable as phenolic standard for HPLC analysis in determination of Sinapic acid derivatives in Canola extracts.[09] 10 g/L of sinapinic acid with solvent was suitable as matrix for ultraviolet laser desorption mass spectrometric determination of proteins.[07] It was also suitable to use as matrix for MALDI-TOFMS and MALDI-ion mobility-TOFMS to determine phospholipids in tissue.[08]
