摘　　要：粗毛淫羊藿Epimedium acuminatum Franch为小檗科植物,又名尖叶淫羊藿,分布于四川、云南、贵州和湖北,在当地作淫羊藿药用。对粗毛淫羊藿的化学成分研究尚未见报道。本文报道从四川产粗毛淫羊藿的地上部分分离到五个化合物并进行了结构研究。A new flavonol glycoside, C_(27)H_(28)O_(10), mp 151～152℃( MeOH),named acuminatin (Ⅰ), was isolated from the aerial part of Epimedium acuminatum Franchin addition to four known compounds. By means of UV, FAB-MS, EI-MS,~1HNMR, ^(13)CNMR and chemical evidences, the structure of acuminatin was establishedas 6', 6' - dimethylpyrano (2', 3': 7, 8) 4' - methyl kaempferol- 3 - O - α - L -rhamnopyranoside. The known compounds were identified as kaempferol-3- O-α- L- rhamnopyranoside (Ⅱ), quercitrin (Ⅲ), hyperin (IV) and daucosterol (Ⅴ).
