Campania is the most important region of Italy in the apricot cultivation, present mostly in the Vesuvio area. At least to the best of our knowledge, no studies are reporting the biochemical characterization of the considerable number of traditional apricot varieties present on this territory, including the qualitative and quantitative profile of the polyphenols present. Our work evaluated the content of β-carotene, total phenolics, phenolic profiles, ascorbic acid and antioxidant activity of 23 traditional varieties of apricots of the Campania region. Principal component analysis (PCA) highlighted that, in the two main groups, the antioxidant activity was strongly affected by the content of ascorbic acid (-0.89), or slightly affected by the content of total polyphenols (-0.67), respect to the content of ascorbic acid (-0.55), never by β-carotene. Chlorogenic acid (up to 55.07 μg g) and catechin (up to 96.15 μg g) resulted the most abundant polyphenols recognized through the chromatographic analysis. PCA, extended to the polyphenol profile, confirmed the distribution of the varieties in two large groups, evidencing once again the hierarchical distance of four varieties ("Panzona", "Paolona" "Baracca" and "Boccucia Eboli") compared to the others.
坎帕尼亚大区是意大利杏树种植最重要的地区，主要集中在维苏威地区。至少就我们所知，尚无研究报道该地区众多传统杏品种的生化特性，包括其中多酚类物质的定性和定量概况。我们的研究评估了坎帕尼亚大区23个传统杏品种的β-胡萝卜素、总酚、酚类物质概况、抗坏血酸含量及抗氧化活性。主成分分析（PCA）表明，在两个主要类别中，抗氧化活性受抗坏血酸含量的强烈影响（-0.89），或受总多酚含量的轻微影响（-0.67），相对于抗坏血酸含量（-0.55），而与β-胡萝卜素含量无关。通过色谱分析鉴定出，绿原酸（含量高达55.07μg/g）和儿茶素（含量高达96.15μg/g）是最丰富的多酚类物质。扩展到多酚类物质概况的主成分分析证实了这些品种分为两大类别，再次表明了四个品种（“潘佐纳”、“保洛纳”、“巴拉卡”和“博库西亚埃博利”）与其他品种之间的层次距离。
