Leírás

Általános leírás

Caffeic acid exists in its free and ester form. It is considered as the predominant polyphenol, contributing to the hydroxycinnamic acid content in various fruits. Coffee is one of the major source of caffeic acid.

Alkalmazás

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.

Biokémiai/fiziológiai hatások

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.

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.
