Procyanidins and Alzheimer’s Disease

Molecular Neurobiology, 2019
Procyanidins, the oligomeric compounds formed from catechin and epicatechin molecules, are potentially effective targets as nutraceuticals or pharmaceuticals in the prevention and treatment of Alzheimer's disease (AD). Natural procyanidins can attenuate AD pathological features, extracellular amyloid deposits, and neurofibrillary tangles via reducing ...

Distribution of procyanidins and their metabolites in rat plasma and tissues in relation to ingestion of procyanidin-enriched or procyanidin-rich cocoa creams

European Journal of Nutrition, 2012
Procyanidins are extensively metabolized via phase-II and microbial enzymes. However, their distribution in the body is not well characterized.This study investigates the distribution of procyanidins (monomers and dimers) and their phase-II metabolites in plasma and tissues (thymus, heart, liver, testicle, lung, kidney, spleen and brain).Wistar rats ...

Metabolism of dietary procyanidins in rats

Free Radical Biology and Medicine, 2003
Procyanidins are major dietary polyphenols made of elementary flavan-3-ol (epi)catechin units. They have antioxidant properties and may contribute to health benefits in humans, but little is known about their metabolic fate. We compared here the metabolism of procyanidin dimer B3, trimer C2, and polymer isolated from willow tree catkins to that of ...

Procyanidin metabolism—A hypothesis

Phytochemistry, 1977
Abstract The experimental evidence relating to the structure, chemical properties and biosynthesis of plant procyanidins is briefly reviewed. A theory is proposed to accommodate this evidence and to correlate the observed increase in polymeric character of the procyanidins as the plant tissue reaches maturity.
