The qualities of plant secondary metabolites as a novel source of natural antioxidants have recently become the focus of research in this field. The current study's objectives were to assess the phytochemical profile, find any natural medicinal compounds present, and determine the antioxidant capacity of two Egyptian toxic plants, Amaranthus viridis (Amaranthaceae) and Lotus corniculatus (Fabaceae) These plants are widespread in Egypt's polluted lands and have not attracted much attention. According to the data, the amounts of linoleic acid, oleic acid, behenic acid, TSFA (total saturated fatty acids), and TUSFA (total unsaturated fatty acids) in the seeds of Lotus corniculatus were 40.13, 28.88, 0.49, 22.14, and 83.62 %, respectively. Additionally, the amounts of linoleic acid, palmitic acid, lignoceric acid, TSFA, and TUSFA in Amaranthus viridis were 45.2, 23.15, 0.13, 19.99, and 75.18 %, respectively. Protein, tanines, HCN, saponins, glycosides, nitrate, essential elements, polyphenolic substances (flavonoids and phenolics), amino acid composition, and antioxidant potential, ABTS•+[2,2-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid)], [DPPH•(2,2-diphenyl-1-picrylhydrazyl) radical scavenging activity, and ferric-reducing antioxidant power (FRAP)] in both plants were quantitatively measured. Both plants include naturally occurring antioxidant chemicals that are clearly capable of removing reactive oxygen species, which then significantly improves the cellular equilibrium (the oxidant/antioxidant process) and protects typical physiological conditions. As a result, the two plantsmay be employed as potential sources of compounds with antioxidant characteristics in the cosmetics, pharmaceutics, and food industries. |
