Sweet cherries (Prunus avium L.) are highly appreciated fruits for their taste, color, nutritional value, and beneficial health effects. In this work, seven new cultivars of sweet cherry were investigated for their main quality traits and nutraceutical value. The phytochemical profile of three classes of phenolic compounds and the antioxidant activity of the new cultivars were investigated through high-performance liquid chromatography with diode array detection (HPLC-DAD) and spectrophotometric assays, respectively, and compared with those of commonly commercialized cultivars. Cyanidine-3-O-rutinoside was the main anthocyanin in all genotypes, and its levels in some new cultivars were about three-fold higher than in commercial ones. The ORAC-assayed antioxidant capacity was positively correlated with the total anthocyanin index. The nutraceutical value of the new cultivars was investigated in terms of antioxidant/neuroprotective capacity in neuron-like SH-SY5Y cells. Results demonstrated that the new cultivars were more effective in counteracting oxidative stress and were also able to upregulate brain-derived neurotrophic factor (BDNF), a pro-survival neurotrophin, suggesting their potential pleiotropic role in counteracting neurodegenerations.

新的甜樱桃品种的果实品质表征是具有抗氧化和神经保护潜力的生物活性酚类化合物的良好来源。

甜樱桃（Prunus avium L.）因其味道，颜色，营养价值和有益健康的作用而受到高度赞赏。在这项工作中，研究了七个新品种的甜樱桃的主要品质特性和营养价值。通过高效液相色谱-二极管阵列检测（HPLC-DAD）和分光光度法分别研究了三类酚类化合物的植物化学特征和新品种的抗氧化活性，并与常用商品品种进行了比较。氰基-3- O芸香糖苷是所有基因型中主要的花色苷，在一些新品种中其含量约为商品化品种的三倍。ORAC测定的抗氧化剂能力与总花青素指数呈正相关。根据神经元样SH-SY5Y细胞的抗氧化/神经保护能力，研究了新品种的营养价值。结果表明，新品种在抵抗氧化应激方面更有效，并且还能够上调脑源性神经营养因子（BDNF）（一种促存活的神经营养蛋白），表明它们在抵抗神经变性方面具有潜在的多效作用。
