The selected A. tricolor accessions contained abundant color attributes, betacyanin, carotenoids, betalains, betaxanthins, and antioxidants potentiality that varied in terms of genotypes. For the first time, we identified 4 betacyanins, and 5 carotenoid compounds in A. tricolor genotypes. The genotype VA14 and VA16 had abundant color attributes, betacyanin such as amaranthine, iso-amaranthine, betanin, iso-betanin, and antioxidants potentiality. These two genotypes having an excellent source of color attributes, betacyanins, betalains, betaxanthins, and antioxidants potentiality could be used as potent antioxidant varieties. The genotype VA11 and VA16 had abundant carotenoid components, such as zeaxanthin, lutein, violaxanthin, neoxanthin, total xanthophylls, and beta-carotene. The genotype VA11 and VA16 had abundant carotenoid components that could be used as carotenoid enrich varieties. It revealed from the correlation study that pigment profiles of A. tricolor genotypes exhibited high quenching capacity of radicals. These accessions have high antioxidant potentials and great opportunity to make drinks, preservatives, and colorant of food products to feed the community deficient in antioxidants. The identified components of betacyanins and carotenoids in A. tricolor require comprehensive pharmacological study. The baseline data on color attributes, betacyanins profile, carotenoids profile, betaxanthins, betalains and antioxidant potentiality obtained in the present study could contribute to pharmacologists for evaluating these components scientifically in A. tricolor.
所选的 A. tricolor 品种含有丰富的颜色属性、甜菜红素、类胡萝卜素、甜菜苷、甜菜黄素和抗氧化潜力，这些属性在基因型上有所不同。我们首次在 A. tricolor 基因型中鉴定出 4 种甜菜红素和 5 种类胡萝卜素化合物。VA14 和 VA16 基因型具有丰富的颜色属性、甜菜红素，如苋菜红、异苋菜红、甜菜苷、异甜菜苷和抗氧化潜力。这两个基因型具有丰富的颜色属性、甜菜红素、甜菜苷、甜菜黄素和抗氧化潜力的来源，可以用作具有强大抗氧化能力的品种。VA11 和 VA16 基因型具有丰富的类胡萝卜素成分，如玉米黄质、叶黄素、玉米黄质、新黄质、总叶黄素和β-胡萝卜素。VA11 和 VA16 基因型具有丰富的类胡萝卜素成分，可以用作类胡萝卜素富集品种。相关性研究表明，A. tricolor 基因型的色素谱表现出高自由基猝灭能力。这些品种具有高抗氧化潜力，有很大机会可以将其用于制作饮料、防腐剂和食品色素，以满足抗氧化剂缺乏的社区的需求。在 A. tricolor 中鉴定出的甜菜红素和类胡萝卜素成分需要进行全面的药理学研究。本研究获得的颜色属性、甜菜红素谱、类胡萝卜素谱、甜菜黄素、甜菜苷和抗氧化潜力的基线数据，可以为药理学家提供科学评估这些成分的依据。
