65 Cacao Polyphenolic Substances 4 . THE ANTHOCYANIN PIGMENTS
The purple colouring matter of cacao cotyledons has been shown to consist oftwo cyanidin glycosides (Forsyth, 1952). In that study the pigments were obtained only as amorphous powders, now known to have been grossly contaminated with colourless glucosides. The anthocyanin which moves the faster on chromatography was incorrectly considered to contain both glucose and arabinose, and the slower an...

متن کاملFlavan 3-ols improve metabolic syndrome risk factors: evidence and mechanisms
Flavan 3-ols, a type of polyphenolic substance, are distributed in a number of plant foods. Of these foods, chocolate is very rich in flavan 3-ols as flavan 3-ol monomers, (+)-catechin and (-)-epicatechin, and the oligomers as procyanidins. There is evidence that cacao products containing flavan 3-ols have the potential to contribute to the risk reduction of cardiometabolic disorders according ...
متن کاملEffects of polyphenol substances derived from Theobroma cacao on gastric mucosal lesion induced by ethanol.
The antiulcer activity of cacao liquor water-soluble crude polyphenols (CWSP) was examined. CWSP, alpha-tocopherol, sucralfate (500 mg/kg), and cimetidine (250 mg/kg) were orally administered to male SD rats 30 minutes before ethanol treatment. 5 ml/kg of ethanol given intragastrically caused lesions in mucosa of the glandular stomach. CWSP caused a reduction of such hemorrhagic lesions as well...
