Metabolism of avenanthramide phytoalexins in oats

Plant Journal, 2004
SummaryOat leaves produce phytoalexins, avenanthramides, in response to infection by pathogens or treatment with elicitors. The metabolism of avenanthramides was investigated using low molecular weight, partially deacetylated chitin as an elicitor. When oat leaf segments are floated on the elicitor solution, avenanthramides accumulate in the solution ...

Biosynthesis of oat avenanthramide phytoalexins

Phytochemistry, 1999
Abstract 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 ...

Identification of a dehydrodimer of avenanthramide phytoalexin in oats

Tetrahedron, 2004
A new compound (1) was found to accumulate when oat leaves were treated with elicitors. A reaction with peroxidase and avenanthramide B, an oat phytoalexin, in the presence of hydrogen peroxide resulted in the formation of 1. The chemical structure of 1 was determined to be a cyclic dehydrodimer of avenanthramide B based on spectroscopic analyses and ...

Analysis of avenanthramides in oat products and estimation of avenanthramide intake in humans

Food Chemistry, 2018
Avenanthramides 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 ...

Stability of Oat Avenanthramides

Cereal Chemistry, 2001
ABSTRACTThe 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
