2-(3,4-Dihydroxyphenyl)-2-((2-(3,4-dihydroxyphenyl)-5,7-dihydroxychroman-3-yl)oxy)chroman-3,4,5,7-tetraol Usage And Synthesis
DescriptionProcyanidin is a polyphenol that exhibits antioxidant activity in a macrocyclic nickel complex-catalyzed Briggs-Rauscher oscillation system.
UsesProanthocyanidins can be useful in the chemical analysis and study of antifungal and antimycotoxigenic activity of tetradenia riparia essential oil and crude extract.
DefinitionChEBI: Procyanidin is oligomeric compounds, formed from catechin and epicatechin molecules. They yield cyanidin when depolymerized under oxidative conditions.
in vivo

The effects of cacao liquor Proanthocyanidin on 2- amino-1-methyl-6-phenylimidazo [4,5-b] pyridine-induced mutagenesis in vivo carcinogenesis in female Sprague-Dawley rats are investigated. In the Ames assay, Proanthocyanidin shows strong antimutagenic effects when assayed in the presence of S-9 mixture. They also inhibit significantly rat pancreatic carcinogenesis in the initiation stage, but not mammary carcinogenesis[1].
