Light radiation promoted stilbene accumulation in peanut sprouts: a response of the reestablishment of oxidant-antioxidant homeostasis

Sargassum vulgare extract as a bio‐elicitor of natural stilbenes production and antioxidant potential in peanut (Arachis hypogaea L.) sprouts

“…Arachis hypogaea is known to be a rich source of stilbenes. Elicitors are widely used to increase the yield of secondary metabolites with attractive bioactivity, but few studies (Yu et al, 2016;Zhu et al, 2020Zhu et al, , 2021 reported the elicitation of stilbenes in peanut sprouts. This study aimed to show that the extract of Sargassum vulgare has significant bioelicitor potential depending on the concentration of the extract and the peanut genotype.…”

“…The addition of phenylalanine combined with ultrasonic treatment increased the resveratrol content of germinating peanuts by a factor of nine (Yu et al., 2016). Similarly, UV irradiation during peanut germination could increase resveratrol content by a factor of 13 (Zhu et al., 2021). We showed that the extract of Sargassum vulgare increased the resveratrol content in germinating ‘Trabelsia’ more than 110‐fold.…”

“…(2005) and Zhu et al . (2021). Except for the biosynthetic pathway of resveratrol, the biosynthesis mechanism of other stilbenes is largely unknown.…”

“…Other studies have linked anthocyanins, antioxidant amino acids and bioactive peptides to the antioxidant activity of legume sprouts (León‐López et al., 2020; Kumari et al., 2021). It is likely that different antioxidant compounds may act synergistically to lead to significant antioxidant activity after elicitor treatment (Zhang et al., 2020; Chung et al., 2021; Zhu et al., 2021).…”

“…(2008) revealed that peanut sprouts are a better source of resveratrol, piceatannol, piceid and antioxidants than peanut kernels. Sprouting is an easy and cheap technique to increase nutritional value, reduce allergenic protein content (Zhu et al., 2021) and accumulate polyphenols, stilbenes, and flavonoids. Lin et al .…”
