Sea buckthorn, a functional food, can provide several nutritious substances useful for human health. As we know, its peels and seeds are removed as inedible parts during processing. However, whether the peels and seeds have the nutritious substances that juice does not. The nutritious metabolites in the peels, juice, and seeds of Shanxi’s wild sea buckthorn were analyzed using ultra-high-performance liquid chromatography-quadrupole exactive Orbitrap mass spectrometry. A total of 456 metabolites were detected. Sixty-five of them were exclusively found in the peels, 55 were exclusively found in the juice, and 130 were exclusively found in the seeds. We found that several flavonoids, purines, nucleotides, and resveratrol were removed during the processing. This meant that we could get only a portion of the nutrition from the sea buckthorn juice in our daily lives. We suggest that peels and seeds should be added in a certain proportion during the processing, in order to obtain more nutrients from sea buckthorn.

沙棘汁，种子和果皮中的代谢物比较（沙棘）

沙棘是一种功能性食品，可以提供多种对人体健康有益的营养物质。众所周知，其果皮和种子在加工过程中被作为不可食用的部分去除。但是，果皮和种子是否具有果汁所没有的营养物质。使用超高效液相色谱-四极杆精确轨道质谱仪分析山西野生沙棘的果皮，果汁和种子中的营养代谢物。总共检测到456种代谢物。其中有65种仅在果皮中发现，55种仅在果汁中发现，而130种仅在种子中发现。我们发现在加工过程中去除了几种类黄酮，嘌呤，核苷酸和白藜芦醇。这意味着我们在日常生活中只能从沙棘汁中获取一部分营养。我们建议加工过程中应按一定比例添加果皮和种子，以从沙棘中获取更多养分。
