And the article was included in Acta Physiologiae Plantarum in 2021.COA of Formula: C14H12O4 This article mentions the following:
The effect of light radiation on stilbene induction and reactive oxygen species (ROS) metabolism of peanut sprouts were explored in this study. Firstly, different types of light sources with same intensity, including white light-emitting diode (LED), UV-A, UV-B and UV-C, were used to radiate peanuts during germination. Results showed contents of stilbenes and total phenolics were significantly promoted by light radiation and different types of stilbene compound were significantly induced in response to different types of light. Secondly, UV-C radiation was selected to treat peanuts with different intensities during germination. Results showed contents of stilbenes, total phenolics, total flavonoids, activity of antioxidant enzymes and phenylalanine ammonia-lyse (PAL) increased significantly with the increasing UV-C intensity. H2O2 showed a remarkable neg. correlation with stilbenes, antioxidants, PAL, peroxidase and catalase. Contents of stilbenes and antioxidants of peanut sprouts could be increased by light radiation effectively in the germination process and the underlying inducing mechanism by UV-C radiation was involved with the mediation of oxidant-antioxidant homeostasis. In the experiment, the researchers used many compounds, for example, (E)-4-(3,5-Dihydroxystyryl)benzene-1,2-diol (cas: 10083-24-6COA of Formula: C14H12O4).
(E)-4-(3,5-Dihydroxystyryl)benzene-1,2-diol (cas: 10083-24-6) belongs to alcohols. Under appropriate conditions, inorganic acids also react with alcohols to form esters. To form these esters, a wide variety of specialized reagents and conditions can be used. Secondary alcohols are easily oxidized without breaking carbon-carbon bonds only as far as the ketone stage. No further oxidation is seen except under very stringent conditions.COA of Formula: C14H12O4
