| Abstract: | Icariin (1) and a new flavone glycoside neoicariin (2) were isolated from the aerial parts of Epimediumsagittatum. Based on spectral analysis including 2D-NMR techniques (1H3H COSY,1H3H NOE, HMQC,HMBC), and chemical methods,the str-ucture of neoicariin (2) was elucidated as 3,5,7-trihydroxy-4'-methoxy-8-(2", 3"-epoxy) isopentylflavone-3-O- a- L-rhamnopyranoside. |
