Metabolic Fate of Orally Ingested Proanthocyanidins through the Digestive Tract

Antioxidants, 2022
Proanthocyanidins (PACs), which are oligomers or polymers of flavan-3ols with potent antioxidative activity, are well known to exert a variety of beneficial health effects. Nonetheless, their bioaccessibility and bioavailability have been poorly assessed.

Salt‐induced nutritional and metabolic shifts in halophytes: implications for food security

Journal of the Science of Food and Agriculture, EarlyView.
Abstract Plant species vary in their response to salinity: some crops show a degree of salt tolerance, while halophytes – whether wild or cultivated – are characterized by a high capacity to thrive under saline conditions. Halophytes are considered a source of valuable secondary metabolites with potential economic value, yet they might also produce ...

Breaking polyphenol–polysaccharide interactions: the promising role of natural deep eutectic solvents

Journal of the Science of Food and Agriculture, EarlyView.
Abstract Food processing generates substantial amounts of byproducts rich in valuable bioactive compounds, particularly polyphenols, known for their antioxidant, anti‐UV, and antimicrobial properties. These molecules hold great potential in sectors such as food, cosmetics, and pharmaceuticals.

Proanthocyanidin Block Arrays (PACBAR) for Comprehensive Capture and Delineation of Proanthocyanidin Structures

Journal of Agricultural and Food Chemistry, 2020
Proanthocyanidins (PACs) are near-ubiquitous and chemically complex metabolites, prototypical of higher plants. Their roles in food/feed/nutrition and ethnomedicine are widely recognized but poorly understood. With the analysis of evidence that underlies this challenge, this perspective identifies shortcomings in capturing and delineating PAC ...

From mainland to islands: the evolution of resistance and tolerance to herbivory in long‐lived oaks

Oikos, EarlyView.
Island biogeography theory predicts that island plants should exhibit reduced defences compared with their mainland relatives due to relaxed herbivory pressure. However, growing empirical evidence challenges this prediction, revealing substantial variation among systems, plant lineages and defence types.

MALDI-TOF MS Analysis of Proanthocyanidins in Two Lowland Tropical Forest Species of Cecropia: A First Look at Their Chemical Structures

Molecules, 2014
The structural chemistry of proanthocyanidin molecules has been investigated in temperate zone plants, but few studies have been done with plants of the Amazonian lowland tropical wet forests where herbivore pressure is more extensive and diverse.

Adaptive Responses of Common and Hybrid Bermudagrasses to Shade Stress Associated With Changes in Morphology, Photosynthesis, and Secondary Metabolites

Frontiers in Plant Science, 2022
Alteration of ploidy in one particular plant species often influences their environmental adaptation. Warm-season bermudagrass is widely used as forage, turfgrass, and ground-cover plant for ecological remediation, but exhibits low shade tolerance ...

The Mysteries of Proanthocyanidin Transport and Polymerization [PDF]

Plant Physiology, 2010
Flavonoids, including proanthocyanidins (PAs; also called condensed tannins), play a multitude of roles in plants ([Winkel-Shirley, 2001][1]). The presence of certain types of flavonoids in crops is associated with desirable and important agronomic traits; therefore, metabolic engineering ...

Bioactive Natural Products in Cardiovascular Disease: Focus on Thrombotic Events

Phytotherapy Research, EarlyView.
An overview of the role of natural products (NP) in cardiovascular disease prevention, highlighting key mechanisms of action: including antiplatelet, antithrombotic, anti‐inflammatory, and antioxidant effects. Additionally, it illustrates the integration of diet–drug interactions, nutritional epigenetics, and the role of artificial intelligence in ...
