Four selected advance lines of drought-tolerant leafy vegetable amaranth were characterized for phenolic profiles, vitamins, and antioxidant activities. The selected advance lines exhibited differences in terms of genotypes with remarkable phenols, vitamins, flavonoids content, and potential radical quenching capacity. We identified twenty-five phenolic and flavonoid compounds including protocatechuic acid, salicylic acid, gentisic acid, gallic acid, β-resorcylic acid, vanillic acid, p-hydroxybenzoic acid, chlorogenic acid, ellagic acid, syringic acid, ferulic acid, kaempferol, m-coumaric acid, trans-cinnamic acid, quercetin, p-coumaric acid, apigenin, caffeic acid, rutin, sinapic acid, isoquercetin, naringenin, myricetin, catechin, and hyperoside. The selected advance lines VA14 and VA16 had abundant phenols, vitamins, flavonoids, and antioxidants potentiality. The selected drought-tolerant leafy vegetable amaranth showed high antioxidant potentiality as phenols, vitamins, flavonoids of these lines had a significant positive correlation with antioxidant capacities equivalent to Trolox using 2,2-diphenyl-1-picrylhydrazyl and ABTS. Therefore, drought-tolerant leafy vegetable amaranth VA14 and VA16 can be grown in semi-arid and drought-prone areas in the world to attaining vitamins and antioxidant sufficiency. The phenolic and flavonoids compounds identified in drought-tolerant leafy vegetable amaranth demand a comprehensive pharmacological study. The baseline data on phenolic and flavonoids compounds obtained in the present study will contribute to the scientist forum for the scientific evaluation of these compounds in vegetable amaranth.
四种耐旱叶用苋菜品系的酚类物质、维生素和抗氧化活性特征。所选的优良品系在基因型方面存在差异，表现在酚类物质、维生素、类黄酮含量和潜在自由基清除能力方面。我们鉴定了 25 种酚类和类黄酮化合物，包括原儿茶酸、水杨酸、龙胆酸、没食子酸、β-间苯二酚、香草酸、对羟基苯甲酸、绿原酸、鞣花酸、丁香酸、阿魏酸、山奈酚、对香豆酸、反式肉桂酸、槲皮素、对香豆酸、芹菜素、咖啡酸、芦丁、芥子酸、异槲皮苷、柚皮苷、橙皮苷、杨梅素、儿茶素和金丝桃苷。VA14 和 VA16 这两个优良品系具有丰富的酚类物质、维生素、类黄酮和抗氧化能力。所选耐旱叶用苋菜具有很高的抗氧化潜力，因为这些品系的酚类物质、维生素和类黄酮与抗氧化能力呈显著正相关，其抗氧化能力相当于 Trolox 使用 2,2-二苯基-1-苦基肼和 ABTS 时的抗氧化能力。因此，耐旱叶用苋菜 VA14 和 VA16 可以在世界上的半干旱和干旱地区种植，以获得足够的维生素和抗氧化剂。耐旱叶用苋菜中鉴定出的酚类和类黄酮化合物需要进行全面的药理学研究。本研究中获得的酚类和类黄酮化合物的基础数据将为科学家提供一个论坛，以对苋菜中的这些化合物进行科学评价。
