Maize is a staple food source in the world, whose ancient varieties or landraces are receiving a growing attention. In this work, two Italian maize cultivars with pigmented kernels and one inbred line were investigated for untargeted phenolic profile, antioxidant capacity and resistance to infection. "Rostrato Rosso" was the richest in anthocyanins whilst phenolic acids were the second class in abundance, with comparable values detected between cultivars. Tyrosol equivalents were also the highest in "Rostrato Rosso" (822.4 mg kg). Coherently, "Rostrato Rosso" was highly resistant to fungal penetration and diffusion. These preliminary findings might help in breeding programs, aiming to develop maize lines more resistant to infections and with improved nutraceutical value.
玉米是世界上的一种主食来源，其古老品种或地方品种正受到越来越多的关注。在这项研究中，对两个具有色素沉着籽粒的意大利玉米品种和一个自交系进行了非靶向酚类成分、抗氧化能力和抗感染能力的研究。“Rostrato Rosso”的花青素含量最高，而酚酸含量次之，不同品种之间的含量相当。酪醇当量在“Rostrato Rosso”中也最高（822.4毫克/千克）。相应地，“Rostrato Rosso”对真菌的侵入和扩散具有高度抗性。这些初步研究结果可能有助于育种计划，旨在培育出更抗感染且具有更高营养保健价值的玉米品系。
