Abstract Understanding the variation in active ingredients of ‘Hupingzao’ during maturity is important for the development of functional jujube products and the efficient use of ‘Hupingzao’ resources. We investigated the metabolic variation of active ingredients of ‘Hupingzao’ at different maturity stages (S1–S5) using widely targeted metabolites. In total, 406 compounds were detected, 191 were annotated by the KEGG database, and 40 active compounds showed significant differences, which may be related to 18 core metabolic pathways. Except for some nucleosides and carbohydrates, the content of most active compounds increased and then decreased with jujube fruit growth. ‘Hupingzao’ was richer in nucleosides and organic acids. The ideal times for the development of eight different active compounds (nucleosides, carbohydrates, organic acids, amino acids, lipids, alcohol, vitamins, and terpenoids) were at seven different maturity stages (S5, S5, S3, S4, S2, S3, and S1), respectively. Widely targeted metabolomics analysis was shown to be a good method to determine the composition of functional jujube compounds. The results of this study serve as a new theoretical reference for functional food experts to promote functional jujube products of ‘Hupingzao’.

‘虎平枣’大枣不同成熟阶段活性成分的广泛靶向代谢组学分析

摘要 了解'虎平枣'成熟期活性成分的变化对于功能性枣产品的开发和'虎平枣'资源的有效利用具有重要意义。我们使用广泛靶向的代谢物研究了不同成熟阶段(S1-S5)'虎平枣'活性成分的代谢变化。共检测到406种化合物,191种被KEGG数据库注释,40种活性化合物表现出显着差异,可能与18条核心代谢途径有关。除部分核苷和碳水化合物外,大部分活性化合物的含量随着枣果实的生长而先增后减。'虎平枣'含有更丰富的核苷和有机酸。开发八种不同活性化合物(核苷、碳水化合物、有机酸、氨基酸、脂质、酒精、维生素和萜类化合物)分别处于七个不同的成熟阶段(S5、S5、S3、S4、S2、S3 和 S1)。广泛靶向的代谢组学分析被证明是确定功能性枣类化合物组成的好方法。该研究结果可为功能性食品专家推广'虎平枣'功能性大枣产品提供新的理论参考。
