The Proanthocyanidin Profile in Beer and Its Raw Materials

Kvasný průmysl, 2015
The presence of proanthocyanidins, substances belonging to the general group of polyphenols in beer is generally rather undesirable due to their tendency to form complexes with proteins, and thereby degrade the colloidal stability of beer.

An unconventional proanthocyanidin pathway in maize

Nature Communications, 2023
AbstractProanthocyanidins (PAs), flavonoid polymers involved in plant defense, are also beneficial to human health and ruminant nutrition. To date, there is little evidence for accumulation of PAs in maize (Zea mays), although maize makes anthocyanins and possesses the key enzyme of the PA pathway, anthocyanidin reductase (ANR).

Synergistic Enhancement of Antioxidant Activity in Arbutus unedo Leaf Extract by Biological Fluids: Implications for Functional and Nutraceutical Applications

Biotechnology and Applied Biochemistry, EarlyView.
ABSTRACT This study examined the effect of biological fluids (saliva, blood plasma, and urine) on the antioxidant capacity of an aqueous extract derived from Arbutus unedo leaves. The extract displayed a concentration‐dependent reducing activity in the ferric reducing power assay (IC50 = 292 ± 7.54 µg/mL) and phosphomolybdenum assays (IC50 = 461.67 ± 4.
