A new flavonol glycoside, C27H28O10, mp 151-152 degrees C (MeOH), named acuminatin (I), was isolated from the aerial part of Epimedium acuminatum Franch in addition to four known compounds. By means of UV, FAB-MS, EI-MS, 1HNMR, 13CNMR and chemical evidences, the structure of acuminatin was established as 6", 6"-dimethylpyrano (2", 3": 7, 8) 4'-methyl kaempferol-3-O-alpha-L-rhamnopyranoside. The known compounds were identified as kaempferol-3-O-alpha-L-rhamnopyranoside (II), quercitrin (III), hyperin (IV) and daucosterol (V).
从尖叶淫羊藿地上部分分离得到一种新的黄酮醇苷，化学式为C27H28O10，熔点151 - 152℃（甲醇），命名为尖叶淫羊藿苷（I），此外还得到四种已知化合物。通过紫外光谱、快原子轰击质谱、电子轰击质谱、核磁共振氢谱、核磁共振碳谱和化学证据，确定尖叶淫羊藿苷的结构为6", 6"-二甲基吡喃（2", 3": 7, 8）4'-甲基山奈酚-3-O-α-L-鼠李糖苷。已知化合物分别鉴定为山奈酚-3-O-α-L-鼠李糖苷（II）、槲皮苷（III）、金丝桃苷（IV）和胡萝卜苷（V）。
