石榴（Punica granatum L.）在全球生产者和消费者中的吸引力正在增加。根据其特性，石榴可用于新鲜食用、工业加工或医疗用途。本研究旨在评估在摩洛哥中部种植的10个石榴品种在矿物质含量和生化特性方面的变异，以更好地了解它们的果实潜力。测定了石榴汁的矿物组成、有机酸、总多酚、花青素含量、单个酚类化合物和抗氧化活性。结果表明，品种间差异显著。酸品种“Lhamdha”富含有机酸、没食子酸酯和鞣花单宁，具有较高的抗氧化活性。因此，它可以作为营养物质的来源。栽培拉拉的“塞夫里”矿物元素含量较高，尤其是碘(I)、钙（Ca）、镁（Mg）、铁（Fe）和银（Ag）。Ouled Abdellah的“Sefri”、Beni Meskine的“Sefri”、“Lahmer”和“Marrakchia”等品种适合生产具有高保健潜力的新鲜石榴汁。事实上，它们富含花青素、多酚、草酸和抗坏血酸，具有很高的抗氧化活性。而Sour Laaz的“Sefri”、Tmassine的“Sefri”、Sidi Abdellah的“Sefri”和Bzeq Tir的“Sefri”则可以用于新鲜水果消费。聚类分析揭示了具有相同称谓“Sefri”的品种间存在差异，证实了石榴品种称谓存在同音同义问题。这项研究清楚地证明了所研究品种的营养和功能潜力，以及它们的价值增值的重要性，特别是对食品和制药工业。
The attractiveness of pomegranate (Punica granatum L.) is increasing worldwide among producers and consumers. Depending on its characteristics, the pomegranate may be intended for fresh consumption, for industrial processing, or for medical purposes. This study aims to assess the variability in terms of mineral content and biochemical properties of ten selected pomegranate cultivars grown in the center of Morocco to better know their fruit potential. Mineral composition, organic acids, total polyphenols, anthocyanins content, individual phenolic compounds, and antioxidant activity were determined in pomegranate juices. Results showed significant differences between cultivars. The sour cultivar “Lhamdha” is rich in organic acids, gallagyl esters, and ellagitannins and showed high antioxidant activity. It could therefore be used as a source for nutraceutical substances. The cultivar “Sefri” of Lalla Takerkoust showed important content of mineral elements, especially iodine (I), calcium (Ca), magnesium (Mg), iron (Fe), and silver (Ag). The cultivars “Sefri” of Ouled Abdellah, “Sefri” of Beni Meskine, “Lahmer,” and “Marrakchia” are suitable for production of fresh pomegranate juice with high potential of health benefits. In fact, they are rich in anthocyanins, polyphenols, and oxalic and ascorbic acids and they presented high antioxidant activity. While the cultivars “Sefri” of Sour Laaz, “Sefri” of Tmassine, “Sefri” of Sidi Abdellah, and “Bzeq Tir” could be intended for fresh fruit consumption. Cluster analysis has revealed the divergence of cultivars with the same appellation “Sefri” confirming the problem of homonymy or synonymy in the pomegranate cultivars appellation. This study clearly demonstrates the nutritional and functional potential of the studied cultivars and the importance of their valorisation, especially for food and pharmaceutical industries.
