Analysis of avenanthramides in oat products and estimation of avenanthramide intake in humans
Food Chemistry, 2018Avenanthramides are phenolic compounds found only in oats, and are of interest due to suggested bioactivities, including anti-inflammatory effects and induction of apoptosis. The objective of this work was to optimise a high performance liquid chromatography (HPLC) method for analysis of avenanthramides in food, and analyse the avenanthramide content ...

Biosynthesis of oat avenanthramide phytoalexins
Phytochemistry, 1999Abstract The biosynthesis of oat phytoalexins, avenanthramides, was investigated by administering labeled putative precursors to oat leaf segments treated with the elicitor, penta-N-acetylchitopentaose. Among the compounds tested, oat leaf segments incorporated [ring-UL-14C]anthranilic acid, [2,3,4,5,6-2H] l -phenylalanine and [1,2-13C]p-coumaric ...

Stability of Oat Avenanthramides
Cereal Chemistry, 2001ABSTRACTThe three main oat avenanthramides, N‐(4′‐hydroxy)‐(E)‐cinnamoyl‐5‐hydroxyanthranilic acid (Bp), N‐(4′‐hydroxy‐3′‐methoxy)‐(E)‐cinnamoyl‐5‐hydroxyanthranilic acid (Bf), and N‐(3′,4′‐dihydroxy)‐(E)‐cinnamoyl‐5‐hydroxyanthranilic acid (Bc), and their corresponding cinnamic acids, p‐coumaric (P), ferulic (F), and caffeic (C), were investigated for

New Dimeric Compounds of Avenanthramide Phytoalexin in Oats
The Journal of Organic Chemistry, 2007Avenanthramide B is an oat phytoalexin produced in response to pathogen attack and elicitation. We found the formation of new dimers (1-5) of avenanthramide B in elicited oat leaves. The dimers were synthesized by a reaction of peroxidase and avenanthramide B in the presence of hydrogen peroxide.

Food & Function
Avenanthramides (Avns), particularly Avn-C, are unique phenolic compounds found in oats, known for their anti-oxidant and anti-inflammatory effects. This study evaluated Avn-C's bioactivity using oxidative damage models in HUVECs induced by t-BOOH and ...

Tentative Avenanthramide‐Modifying Enzyme in Oats
Cereal Chemistry, 2003ABSTRACTA decrease of the concentration of the synthetic avenanthramide N‐(4′‐hydroxy‐(E)‐cinnamoyl)‐5‐hydroxyanthranilic acid in a buffered slurry of milled oat groats (Avena sativa L.) was temperature and pH‐dependent, with a maximum rate at 30°C and pH 9.

Avenanthramide-C prevents amyloid formation of bovine serum albumin
Biophysical Chemistry, 2020The misfolding of protein and its assembly into amyloid fibrils with a characteristic β-sheet-rich secondary structure, cause a lot of illnesses. Polyphenols have been extensively studied as a class of amyloid inhibitors, whose effect depends on the position and number of hydroxyl groups around the flavone backbone.

Microbial‐derived metabolites of oat avenanthramides
The FASEB Journal, 2016Oat is a multifunctional crop nutritionally superior to many other unfortified cereals. It is commonly consumed as whole grains and known to provide healthy nutrients to humans. Oats contain a unique type of compounds, avenanthramides (AVAs), which are a group of substituted N ...
