Rosehips are a prominent source of numerous bioactive compounds. However, despite their extensive potential, the metabolic profiles among different rosehip species have not been fully elucidated. In this study, 523 secondary metabolites from rosehips of 12 Rosa species were identified using ultra-high-performance liquid chromatography-tandem mass spectrometry. They were primarily composed of flavonoids and phenolic acids. A K-means analysis revealed the characteristic metabolites in different rosehips. For example, R. persica contained a more abundant supply of phenolic acids, while R. roxburghii harbored a richer array of terpenoids. A total of 73 key active ingredients were screened from traditional Chinese medicine databases, and they indicated that R. persica is more promising for use in functional foods or health supplements compared with the other fruits. Moreover, a differential analysis identified 47 compounds as potential contributors to the astringent taste of rosehips, including ellagic acid 4-O-glucoside and cadaverine. This study provides valuable information to develop new functional foods of rosehips and improve the quality of their fruits.
玫瑰果是多种生物活性化合物的重要来源。然而，尽管它们具有广泛的潜力，但不同玫瑰果品种之间的代谢谱尚未完全阐明。在本研究中，使用超高效液相色谱-串联质谱法鉴定了12种蔷薇属玫瑰果中的523种次生代谢物。它们主要由黄酮类化合物和酚酸组成。K均值分析揭示了不同玫瑰果中的特征性代谢物。例如，波斯蔷薇含有更丰富的酚酸，而刺梨含有更丰富的萜类化合物。从中药数据库中筛选出73种关键活性成分，结果表明与其他果实相比，波斯蔷薇在功能性食品或健康补充剂方面更具应用前景。此外，差异分析确定了47种化合物可能是玫瑰果涩味的潜在成因，包括鞣花酸4-O-葡萄糖苷和尸胺。本研究为开发新型玫瑰果功能性食品和提高其果实品质提供了有价值的信息。
