Measuring antioxidant activity in yellow corn (Zea mays L.) inbreds from three different geographic regions

Abstract Corn ( Zea mays L.) provides a major source of calories for human consumption and therefore, the nutritional components corn have large impact on health. For example, kernels contain antioxidants, such as polyphenols (including anthocyanins other flavonoids) carotenoids. Such compounds represent useful targets biofortification breeding. In this study, we used 34 inbred lines from three different regions (East Asia, Southern subtropical regions) 11 F 1 hybrids derived inbreds to investigate antioxidant activity in yellow corn. We compared methods measuring test their consistency determine whether color could be an indicator activity. also measured carotenoid levels No difference was detected between temperate vs. tropical regions. determined that is contributor kernel color, especially yellowness, These findings lay foundation by providing information about correlations among contents, identifying easy method assess
