Extensive epidemiological and clinical evidence associates diets high in flavanol-containing foods with cardiovascular health benefits in humans. Catechin and epicatechin, the most common flavanols in foods, are present in the diet in different enantiomeric forms. This study investigated the influence of the stereochemical configuration of flavanols on

A new flavanol from Daphne genkwa
Fitoterapia, 2007A new flavanol, 5, 7, 4'-trihydroxy-8-ethoxycarbonylflavanol (1), was isolated from the ethanol extract of Daphne genkwa Sieb. et Zucc. Its structure was defined by spectroscopic methods.

Nuclei of Tea Flowers As Targets for Flavanols
Plant Biology, 2004Abstract: The tea plant (Camellia sinensis L.) is famous for its flavanol‐based constituents being valuable for human health. These flavanols associate with the nuclei of tea flowers, which is demonstrated histochemically by blue colouration using the selective staining reagent p‐dimethylaminocinnamaldehyde (DMACA).

Chromatographic separation and automated analysis of flavanols
Analytical Biochemistry, 1978Flavanols from barley or hops were separated chromatographically and assayed automatically by reaction with the chromogen, 4-dimethylaminocinnamaldehyde. For separating the flavanols on Sephadex G-25, gradient elution with water-methanol mixtures was necessary. The chromogen was specific for flavanols and well suited to AutoAnalyzer methods. The method

Antioxidant properties of ferrous flavanol mixtures
Food Chemistry, 2018Interaction of metal, especially iron ions with flavanols is considered as an important feature of these compounds and is believed to contribute to their both antioxidant and prooxidant properties. The aim of this study was to examine how Fe2+ binding to form a 4:1 (flavanol:Fe2+) mixtures affects the antioxidant properties of flavanols.

Cocoa Flavanol Supplementation and Exercise: A Systematic Review
Sports Medicine, 2018Cocoa flavanols (CFs) have antioxidant and anti-inflammatory capacities and can improve vascular function. It has recently been suggested that CF intake may improve exercise performance and recovery. This systematic review aimed to evaluate the literature on the effects of CF intake on exercise performance and recovery and exercise-induced changes in ...

Circular dichroism spectra of flavanols
Tetrahedron, 1971Abstract CD spectra of the flavanols (+) catechin, (−) robinetinidol, (+) afzelechin, (−) epiafzelechin, (−)epicatechin, (−) epigallocatechin, (+) fisetinidol and (+) epifisetinidol are reported at 25° and −185°. At −185° the contributions of the two aromatic chromophores to the ′L b transition can be separated.

Flavanols, which are widely distributed in plant sources, constitute an important subclass of flavonoids. Cocoa, various types of tea, and several fruits (such as apples, grapes, apricots, peaches, and blueberries) are rich in these compounds. In recent years, these compounds have attracted considerable attention due to their potential beneficial ...
