Regular consumption of tomatoes has been associated with decreased risk of chronic degenerative diseases. Epidemiological findings confirm the observed health effects are due to the presence of different antioxidant molecules such as carotenoids, particularly lycopene, ascorbic acid, vitamin E and phenol compounds, particularly flavonoids. In this work, eight components contributing to the healthy quality of tomato (i. e. lycopene, beta-carotene, other carotenoids, flavonoids, phenolic acids, vitamins C and E, dry residue) were studied in the framework of breeding programs aiming to develop nutritional superior genotypes. Twelve tomato advanced breeding lines and six open pollinated cultivars were grown in strictly controlled conditions and analysed for their content of antioxidants. Among the 18 genotypes analysed, 10 showed a high level of total carotenoids, 6 high level of beta-carotene, 9 high lycopene levels, 15 high flavonoids and 2 relevant concentration of vitamin E. Based on such data and on a literature survey on tomato composition, an index, called index of antioxidant nutritional quality (I(QUAN)), was proposed as a tool to address the breeding programs in selecting tomato genotypes with antioxidant nutritional qualities.
经常食用番茄与慢性退行性疾病风险降低有关。流行病学研究结果证实，观察到的健康益处归因于番茄中存在不同的抗氧化分子，如类胡萝卜素（尤其是番茄红素）、抗坏血酸、维生素E以及酚类化合物（尤其是黄酮类化合物）。在这项研究中，为培育营养更优的番茄基因型，在育种计划框架内研究了影响番茄健康品质的八个成分（即番茄红素、β-胡萝卜素、其他类胡萝卜素、黄酮类化合物、酚酸、维生素C和E、干物质）。12个番茄高级育种系和6个开放授粉品种在严格控制的条件下种植，并分析其抗氧化剂含量。在所分析的18个基因型中，10个表现出总类胡萝卜素含量高，6个β-胡萝卜素含量高，9个番茄红素含量高，15个黄酮类化合物含量高，2个维生素E含量可观。基于这些数据以及对番茄成分的文献调查，提出了一个名为抗氧化营养品质指数（I(QUAN)）的指标，作为在选择具有抗氧化营养品质的番茄基因型时指导育种计划的工具。
