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).

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.

Guideline for High‐Performance Liquid Chromatography Detection of Anthocyanins
AgriFood: Journal of Agricultural Products for Food, EarlyView.ABSTRACT Anthocyanins, as water‐soluble natural pigments widely present in plants, have various biological activities such as antioxidation and anti‐inflammatory, and are widely used in the fields of food, cosmetics, and medicine. However, because of the presence of unstable phenolic hydroxyl groups in their structure, they are prone to degradation due
