The aim of this work was to investigate the influence of two locations and seven cultivars on the profiling of metabolites in organically grown plums ( L.) fruit in Norway. P, K, and Ca were most abundant in the studied fruits, while Ba and Sr formed a clear line between the locations. The most abundant sugars were glucose, fructose, sucrose, and sorbitol, which together accounted for up to 97.00%. Quinic acid and malic acid were the predominant organic acids, while chlorogenic acid, rutin, and kaempferol-3--glucoside were the most abundant polyphenols. Plums from Ullensvang were characterized by a higher content of minerals, sugars, organic acids, total polyphenol content (TPC), and radical scavenging activity (RSA), while plums from Telemark had a higher content of quantified polyphenols. The cultivar 'Mallard' had the highest mineral and radical scavenging activity, 'Opal' had the sweetest fruit, 'Jubileum' had the highest acidity, 'Excalibur' had the highest TPC content, and 'Valor' stored the highest content of quantified polyphenols, especially chlorogenic acid. These results provide comprehensive information on the chemical profiles of selected plum cultivars, suggesting that organic plums are a rich source of beneficial compounds that can have a positive impact on human health.
这项工作的目的是研究挪威两个产地和七个品种对有机种植李子（李属）果实代谢物谱的影响。在所研究的果实中，磷、钾和钙含量最为丰富，而钡和锶在不同产地之间形成了明显的区分。含量最丰富的糖类为葡萄糖、果糖、蔗糖和山梨醇，它们总计占比高达97.00%。奎尼酸和苹果酸是主要的有机酸，而绿原酸、芦丁和山奈酚-3-O-葡萄糖苷是含量最丰富的多酚类物质。来自于尤伦斯旺的李子特点是矿物质、糖类、有机酸、总多酚含量（TPC）和自由基清除活性（RSA）较高，而来自泰勒马克的李子定量多酚含量较高。品种“绿头鸭”具有最高的矿物质和自由基清除活性；“欧泊”果实最甜；“禧年”酸度最高；“王者之剑”TPC含量最高；“英勇”储存的定量多酚含量最高，尤其是绿原酸。这些结果提供了有关所选李子品种化学特征的全面信息，表明有机李子是有益化合物的丰富来源，对人类健康可能产生积极影响。
