淫羊藿甙(icariin,1)和1个新的黄酮甙类成分-新淫羊藿甙(neoicariin,2)已从中药淫羊藿(Epimedium sagittatum)的地上部分分到,新淫羊藿甙(2)的化学结构经光谱分析并通过1H1H COSY,1H-1HNOE,HMQC,HMBC等二维核磁共振谱和化学方法鉴定为3,5,7-三羟基-4'-甲氧基-8-(2",3"-环氧)异戊基黄酮-3-Q-α-L-鼠李吡喃糖甙.
淫羊藿甙(icariin,1)和1箇新的黃酮甙類成分-新淫羊藿甙(neoicariin,2)已從中藥淫羊藿(Epimedium sagittatum)的地上部分分到,新淫羊藿甙(2)的化學結構經光譜分析併通過1H1H COSY,1H-1HNOE,HMQC,HMBC等二維覈磁共振譜和化學方法鑒定為3,5,7-三羥基-4'-甲氧基-8-(2",3"-環氧)異戊基黃酮-3-Q-α-L-鼠李吡喃糖甙.

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.
