Abstract The European dewberry (Rubus caesius) is a perennial shrub that is widely distributed in Europe but can also be found in North America. In folk medicine, the European dewberry is used to treat hyperglycaemia, diarrhoea and inflammation. LC-MS analysis of the European dewberry confirmed the presence of 35 compounds, mostly flavonoids, phenolic acids and derivatives of ellagic acid. Phytochemical analysis of R. caesius leaves led to the isolation of nine phenolics, namely: quercetin 3-O-β-D-rutinoside (1), kaempferol 3-O-β-D-glucuronide (2), quercetin 3-O-β-D-glucuronide (3), methyl brevifolincarboxylate (4), kaempferol 3-O-β-D-(6″-O-(E)-p-coumaroyl)-glucoside (5), kaempferol (6), quercetin (7), pedunculagin (8), and ellagic acid (9). Compounds 1–8 were isolated from this species for the first time. The chemophenetic significance was discussed.

Rubus caesius（蔷薇科）的次级代谢产物

摘要 欧洲露莓（Rubus caesius）是一种多年生灌木，广泛分布于欧洲，但也可以在北美找到。在民间医学中，欧洲露莓用于治疗高血糖、腹泻和炎症。欧洲露莓的 LC-MS 分析证实了 35 种化合物的存在，主要是类黄酮、酚酸和鞣花酸衍生物。R. caesius 叶子的植物化学分析导致​​分离出九种酚类物质，即：槲皮素 3-O-β-D-芸香苷 (1)、山奈酚 3-O-β-D-葡萄糖苷酸 (2)、槲皮素 3-O- β-D-葡萄糖醛酸 (3)、短叶黄素甲酸甲酯 (4)、山奈酚 3-O-β-D-(6″-O-(E)-p-香豆酰)-葡萄糖苷 (5)、山奈酚 (6)、槲皮素(7)、花梗素 (8) 和鞣花酸 (9)。化合物 1-8 为首次从该物种中分离得到。
