flavonoid

Herbal medicine
Any of a family of yellow pigments which are chemically similar to tannins and somewhat similar in use; flavonoids have been used for bruising, hay fever and menorrhagia. 

Nutrition
A family of biologically active polyphenolic compounds found in fruits (in particular in the pulp thereof), vegetables, tea and red wine, which are potent antioxidants and effective platelet inhibitors; a flavonoid-rich diet may protect against atherosclerosis and platelet-mediated thrombosis, due to flavonoids’ platelet-inhibition.

Mars' studies have shown cocoa flavanols have a range of benefits in humans, including improved circulation and cardiovascular health.
Cocoa beans fresh from the tree are exceptionally rich in flavanols. Unfortunately during conventional chocolate making this high antioxidant capacity is greatly reduced due to high temperature manufacturing processes.

"It would be unfortunate if people consumed hundreds of calories a day from confectionery chocolate, thinking they're helping themselves," says Harvard flavanol researcher Naomi Deirdre Fisher.
'Research that compared the flavanol content of 41 different commercial brands of dark and milk chocolate has shown no correlation between the percentage of cocoa and the flavanol content,' says Dr Ried.
b) Flavanols have two forms: Catechin in monomer structure and proanthocyanidin in polymer structure.
Italian researchers reviewed a number of studies investigating how cocoa flavanols affected various cognitive domains.
(https://www.ncbi.nlm.nih.gov/pubmed/15190043) Previous research proposes cocoa and cocoa-containing foods, like dark chocolate, possess heart health benefits because their high flavanol content promotes the healthy function of blood vessels.

A decrease of native monomeric anthocyanins with MOx was detected in agreement with reported results (18-22-47) and can be related to the involvement of these molecules in the oxygen-activated reactions between anthocyanins and flavanols. These reactions determine the formation of anthocyanin-ethyl flavanol compounds, which are unstable and may undergo cleavage of the ethyl bridge with consequent liberation of monomeric anthocyanins.
