Data (mg kg–1) is presented as mean ± SD and represents mean of three independent measurements. n/d = not detected (i.e., below the detection level). Values with unlike letters (a-g) within the same column differ significantly (p < 0.05). AVNs 2c, 2f, and 2p are esters of 5-hydroxyanthranilic acid with caffeic (2c aka C), p-coumaric (2p aka A), and ferulic (2f aka B) acids. AVNa and AVNb are unknown avenanthramides.
