Bee pollen, a beehive product collected from flowers by honeybees, contains over 250 biological substances, and has attracted increasing attention as a functional food. However, commercial bee pollen products are often multifloral, and samples from different countries vary significantly. There is no universal standard for objective quality assessment of bee pollen based on its chemical composition. Here, we report metabolomic analysis of 11 bee pollen samples from Spain, China, and Australia for quality control. The characteristics of the samples depend on the sucrose, nucleoside, amino acid, and flavanol concentrations. Bee pollen samples from Spain and Australia had higher sucrose and adenosine concentrations, whereas those from China had higher trigonelline, uridine, and cytidine concentrations. Interestingly, acetic acid was only detected in samples from China. These components can be used to identify the country of origin. The obtained profiles of the samples will contribute to universal standard development for bee pollen products.
蜂花粉是蜜蜂从花朵中采集的蜂巢产品，含有250多种生物物质，作为一种功能性食品受到越来越多的关注。然而，市售蜂花粉产品往往是多花的，且来自不同国家的样本差异显著。目前尚无基于化学成分对蜂花粉进行客观质量评估的通用标准。在此，我们报告了对来自西班牙、中国和澳大利亚的11个蜂花粉样本进行代谢组学分析以进行质量控制。样本的特征取决于蔗糖、核苷、氨基酸和黄烷醇的浓度。来自西班牙和澳大利亚的蜂花粉样本蔗糖和腺苷浓度较高，而来自中国的样本胡芦巴碱、尿苷和胞苷浓度较高。有趣的是，仅在中国的样本中检测到了乙酸。这些成分可用于识别原产国。所获得的样本概况将有助于制定蜂花粉产品的通用标准。
