Abstract：
The fruit of the jujube tree is high in nutrients and has various health benefits. China is a major producer of jujube, and it is now cultivated all around the world. Numerous studies have demonstrated the nutritional value and potential health advantages of bioactive compounds found in the jujube tree. Furthermore, the jujube tree has a remarkable 7000-year agricultural history. The jujube plant has developed a rich gene pool, making it a valuable resource for germplasm. Different studies have focused on the developmental stages of jujube fruits to identify the optimal time for harvest and to assess the changes in their bioactive natural compounds or products during the process of development but the molecular mechanism underlying the production of bioactive natural products in Z. jujuba is still poorly understood. Moreover, the potential differential expressed genes (DEGs) identified as responsible for the synthesis of these compounds should be further functionally verified. It has been noticed that the contents of total flavonoids, total phenolic, and vitamin C increase significantly during the ripening process, while the contents of soluble sugars and organic acids decrease gradually. In this review, we have also scrutinized the challenges that hinder the utilization of jujube fruit resources and suggested potential areas for further research. As such, our review serves as a valuable resource for the future development of jujube-based nutritional compounds and the incorporation of their nutritional elements into the functional foods industry.
摘要：
枣树的果实营养丰富，具有多种健康益处。中国是大枣的主要生产国，它现在在世界各地种植。大量研究已经证明了在枣树中发现的生物活性化合物的营养价值和潜在的健康优势。此外，枣树有显著的7000年的农业历史。枣属植物发展了丰富的基因库，使其成为宝贵的种质资源。不同的研究集中在枣果实的发育阶段，以确定收获的最佳时间，并评估其生物活性天然化合物或产物在发育过程中的变化，但对Z枣产生生物活性天然产物的分子机制仍然知之甚少。此外，被鉴定为负责合成这些化合物的潜在差异表达基因（DEGs）应进一步进行功能验证。人们注意到，总黄酮的含量，总酚,维生素C在成熟过程中显著增加，可溶性糖和有机酸含量逐渐下降。在这次审查中,我们还仔细研究了阻碍枣果资源利用的挑战，并提出了进一步研究的潜在领域。因此，我们的评论为未来开发基于枣的营养化合物以及将其营养元素纳入功能食品行业提供了宝贵的资源。
