As a class of plant polyphenolic compounds contained in some forages (i.e., sainfoin [Onobrychis viciifolia Scop.], big trefoil [Lotus pedunculatus Cav.], birdsfoot trefoil [Lotus corniculatus L.]), condensed tannins (CTs), also referred to as proanthocyanidins (PAs or PACs), exhibit a variety of biological effects on ruminants. The potential positive impact of CTs on the agricultural industry stems from their ability to modulate proteolysis during forage conservation and ruminal digestion, to prevent bloat, to reduce intestinal parasite burdens, to abate methane and ammonia emissions from ruminants, and to inhibit the activity of soil‐nitrifying bacteria. How CTs exert these effects on ruminants focuses on the interaction of CTs with proteins. The structure‐activity relationship in CT–protein interaction is not well understood but is known to be dependent on the structure and properties of both the CT and the protein. The purpose of this perspective is fivefold. First, we provide the reader with a better understanding of the structural diversity of CTs present in plant material and enable the reader to appreciate that not all CTs are the same. Second, we provide examples of how CT structural diversity affects the interaction of CTs with the protein, which, in turn, dictates the biological response from the animal. Third, we describe the hurdles in obtaining highly pure and well‐characterized CTs from natural sources for use in studies to attempt to elucidate how CTs impart each biological effect. We then describe improved and emerging techniques for CT analysis and, finally, we conclude this perspective with questions to address in future investigations and forward a list of recommendations for CT researchers to follow.

“…Wine samples were directly fractionated by gel permeation chromatography (GPC) on a Toyopearl gel HP-50 F column as described by Fernández, Martínez, Hernández, Guadalupe, and Ayestarán (2011) and Guadalupe, Soldevilla, Sáenz-Navajas, and Ayestarán (2006). Fractionation was performed in triplicate and phloroglucinol adducts were analysed in F2 fractions by reversed-phase HPLC as described by Kennedy and Jones (2001).…”

This research studies the sensory properties and chemical composition of varietal wines made with minority varieties from La Rioja (Spain) and it analyses the transformations in phenolic compounds and colour parameters occurring during the malolactic fermentation. In this sense, all the analysed parameters underwent changes of the same magnitude during this stage and both anthocyanin and hydroxycinnamic acid distribution was found to be dependent on the grape variety and not on the winemaking process. Wines made with these varieties showed high values of resveratrol that could lead to healthier wines, and the variety Maturana Tinta de Navarrete was found to share quite similarities in the chemical parameters with Tempranillo, studied as a reference variety. In the sensory analysis, and although all the wines obtained good punctuations, Monastel and Maturana Tinta de Navarrete were the best valued. Monastel had the highest colour intensity and both varieties showed high aromatic intensity and great complexity. In mouth, Monastel showed the greater persistence, mount length and structure and Maturana Tinta de Navarrete was described as fresh and pleasant. In conclusion, this research shows the first characterization of these wines and provides data to be used as a chemotaxonomic tool to fingerprint them. Moreover, it opens the door to the use of minority varieties providing a viable alternative to traditional grape varieties cultivated in La Rioja and favouring consumer offer and wine differentiation.

“…Among the CE methods, Sakodinskaya et al [14] used borate buffer for the assay of HQ, Glockl et al [15] analyzed the AR metabolites in human urine after oral intake of bearberry leaves. There also are some capillary zone electrophoresis (CZE) methods for phenolic compounds in olive oils [16][17][18], honey [19] and wine [20,21]. None of them have applied CE for the determination of AR, KA and HQ in skin whitening cosmetics.…”
