title: [Acuminatin from the aerial part of Epimedium acuminatum].
abstract: 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).
