Description

Description générale

Cafteric acid (CFA) is a polyphenolic compound belonging to the hydroxycinnamic acids (HCAs) subgroup. It is a derivative of caffeic acid. Cafteric acid is mainly sourced from Echinacea purpurea.

Application

Caftaric acid has been used:

• as a standard antioxidant to determine the antioxidant potential (AOP) of red wine using 2,2-diphenyl-1-picrylhydrazyl (DPPH) assay
• as an antioxidant together with sulfur dioxide (SO₂) to measure the antioxidant potential of white wines using 2,2-diphenyl-1-picrylhydrazyl (DPPH) and Folin-Ciocalteu (FC) assays
• to evaluate the myelopoietic effect on bone marrow of rats treated with various Echinacea purpurea extracts
• to identify (poly)phenolic compounds in concord grape juice and their metabolites in human plasma and urine after juice consumption

Actions biochimiques/physiologiques

Caftaric acid exerts antioxidant and anti-inflammatory effects against indomethacin-induced gastric ulcers in rats. It also displays antimutagenicity properties.
