Improvement of nutritional characteristics and other health benefits of processed maize food products
… Spectroscopy (FTIR), but the insoluble-bound hydroxycinnamic acids were difficult to quantify using standard extraction protocols. Therefore, at the onset of the project, a high-throughput method for the extraction of insoluble-bound hydroxycinnamic acids was developed (Chapter 1). The overall …

The supramolecular modification of trans-resveratrol and related antioxidant molecules
… the beneficial effects of red wine. The phenolic hydroxycinnamic acids caffeic acid (CAF), ferulic acid (FA), p-coumaric acid (PCA) and sinapic acid (SA) are found in a wide variety of plants and also have antioxidant activity. The acetophenone derivatives paeonol (2H4M) and vanillin (4H3M) …

Novel Sulfated 4-Hydroxycinnamic Acid Oligomers as Potent Anticoagulants
… chemo-enzymatically prepared oligomers of 4-hydroxycinnamic acids (DHPs) as potential anticoagulants. Oligomers were prepared through peroxidase-catalyzed oxidative coupling of 4-hydroxycinnamic acids. The products resulting from this reaction are called CDs, FDs and SDs. Structurally, these …

Natural Variability in Phenolic and Sesquiterpene Constituents Among Burdock (<i>Arctium lappa</i> L. and <i>Arctium minus</i> L.) Leaves for Potential Medicinal Interests
… high levels of variability for flavonoids and hydroxycinnamic acids among accessions and among plants within accessions. In general, <i>A. minus</i> plants contained more quantifiable chromatographic compounds (peaks) than those of <i>A. lappa</i>. <i>Arctium lappa</i> individuals produced …

Benzoic acid regulates the physio-biochemical responses of chia (Salvia hispanica L.) seedlings under salinity stress
… strategies, including the secretion of phenolic acids in response to environmental stresses. Phenolic acids can be categorised into different subclasses based on their chemical structures, such as hydroxybenzoic acids and hydroxycinnamic acids. Among them, benzoic acid (B.A) serves as a signaling …

Chemistry of hydroxycinnamate esters and their role as precursors to Dekkera produced off-flavour in wine.
… studied with respect to the breakdown of the hydroxycinnamic acids, p-coumaric and ferulic acid, by D. bruxellensis. The presence of esterified hydroxycinnamate conjugates in grapes and wine is well established and they account for a large proportion of the hydroxycinnamate content. There …

Formation of Maillard Reaction Products and Chlorogenic Acid-Quinone Induced Green Pigments in Gluten-Free Pretzels Made Using Sunflower Flour
… CGA and instead revealed the presence of non-CGA hydroxycinnamic acids (HCAs) such as caffeic, ferulic, and <em>p-</em>coumaric acid. The mixture containing HF 55 had the highest Schiff base, CGA, melanoidin, and green TBA content. There was no significant difference in CGA and MRPs between …

Investigating the modulation of oral drug absorption using in vitro models
… (results that support previous studies). Hydroxycinnamic acids had no effect on p-glycoprotein. Studies on other compounds found that the balance between inhibiting p-glycoprotein and disrupting cell membranes depends on the compound containing an oxygen atom and the size of the negative …

Hull, ferulic acid, para-coumaric acid content and particle size characteristics of various barley varieties in relation to nutrient availability in ruminants
… energy relative to corn. Barley grain contains hydroxycinnamic acids (mainly ferulic acid (FA) and ñ-coumaric acid (PCA)) which are cross-linked to polysaccharides, therefore, limit cell wall degradability in the rumen. Paricle size of barley grain also affects the digestion of barley in the …

Determination of bioactive and potentially toxic compounds in food: raw material analysis and shelf life evaluation
… and lipidic substances such as n-3 fatty acids, tocopherols and sterols. Phenolic compounds, tocopherols and sterols are present in all plants and have been studied extensively in cereals, nuts and oil. n-3 fatty acids are present in fish and all around the vegetable kingdom. The aim of …
