“…As the result, the total amount of AVNs of three showed a gradually increase in 196 h. Within 48 h, both AVN-A and AVN-C presented the parallel increases of their content, while AVN-B remained low level relative to other two AVNs. However, the content of AVN-C decreased continuously after 48 h, where AVN-B content gradually increased and reached the highest level of three AVNs at 196 h along with the total AVNs content [ 101 ]. The similar result also observed in the Wu’s study.…”

“…The germinating oats treated with methyl jasmonate (MeJA) or abscisic acid (ABA) could yield a 2.5-fold (582.9 mg/kg FW) and 2.8-fold (642.9 mg/kg FW) increase in the AVN content relative to untreated controls (232.6 mg/kg), respectively [ 106 ]. Later, to increase the proportion of AVN-C in total AVNs, single or combined treatments with ABA and ascorbic acid (Asc) during the steeping or germination period was performed [ 101 ]. Compared to the control (541 μg/g dry weight), the 300 μM-ABA treatment during the steeping period significantly increased the proportion of AVN-C in total AVN (1.8- fold).…”

Oats ( Avena sativa L.) are one of the worldwide cereal crops. Avenanthramides (AVNs), the unique plant alkaloids of secondary metabolites found in oats, are nutritionally important for humans and animals. Numerous bioactivities of AVNs have been investigated and demonstrated in vivo and in vitro . Despite all these, researchers from all over the world are taking efforts to learn more knowledge about AVNs. In this work, we highlighted the recent updated findings that have increased our understanding of AVNs bioactivity, distribution, and especially the AVNs biosynthesis. Since the limits content of AVNs in oats strictly hinders the demand, understanding the mechanisms underlying AVN biosynthesis is important not only for developing a renewable, sustainable, and environmentally friendly source in both plants and microorganisms but also for designing effective strategies for enhancing their production via induction and metabolic engineering. Future directions for improving AVN production in native producers and heterologous systems for food and feed use are also discussed. This summary will provide a broad view of these specific natural products from oats.
