Abstract

nutrients are closely related to consumer health. In this study, the contents of 22 amino acids in four glutinous rice varieties were quantified by LC-MS-targeted metabolomics, and the relationships between nutritional components and metabolites were analysed. The results demonstrated that gingerglycolipid B and pantothenic acid were significantly negatively correlated with Ala. The Lys and Cys-Cys contents of ZN18 and YZN were significantly higher than those of YCN and ZN20. Citric acid was significantly positively correlated with Lys and Cys-Cys. The ascorbic acid content of YZN and ZN18 was significantly higher than that of YCN and ZN20. YZN had the highest Mn, Zn, Ca, and crude fat contents. Gingerglycolipid B and pantothenic acid were significantly negatively correlated with Mn and Zn. Gingerglycolipid B and pantothenic acid are closely related to other nutritional components, and they are important metabolites formed by the nutrient components of purple glutinous rice.

摘要

营养素与消费者健康密切相关。本研究采用 LC-MS 靶向代谢组学方法定量测定了四种糯米品种中 22 种氨基酸的含量，并分析了营养成分与代谢物之间的关系。结果表明，姜烯糖苷 B 和泛酸与 Ala 呈显著负相关。ZN18 和 YZN 的 Lys 和 Cys-Cys 含量明显高于 YCN 和 ZN20。柠檬酸与 Lys 和 Cys-Cys 呈显著正相关。YZN 和 ZN18 的抗坏血酸含量明显高于 YCN 和 ZN20。YZN 的 Mn、Zn、Ca 和粗脂肪含量最高。姜烯糖苷 B 和泛酸与 Mn 和 Zn 呈显著负相关。姜烯糖苷 B 和泛酸与其他营养成分密切相关，是紫糯米营养成分形成的重要代谢产物。
