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
Biochem/physiol Actions:	Caftaric acid exerts antioxidant and anti-inflammatory effects against indomethacin-induced gastric ulcers in rats. It also displays antimutagenicity properties.
General description:	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.
Packaging:	Bottomless glass bottle. Contents are inside inserted fused cone.
