Application

Caffeic acid has been used as a standard of phenolic acid in the study to determine the total phenolic acid content in vegetables after subjecting to alkaline and acid hydrolysis. It has also been used to determine its antioxidant activity by various assay methods.

Biochem/physiol Actions

A natural dietary phenolic compound found in plants that is an anti-oxidant. Inhibits the synthesis of leukotrienes that are involved in immunoregulation, inflammation and allergy. Inhibits Cu2+-induced LDL oxidation.
Anti-oxidant phenolic compound found in plants; Inhibits the synthesis of leukotrienes.
Caffeic acid and other polyphenols are metabolized by going through enzyme catalysed methyl transfer, sulfation and glucuronic acid addition. It non-competitively prevents the action of 5-lipoxygenase. Caffeic acid ready undergoes hydrolysis in alkaline conditions.
