Abstract
A new flavonol glycoside, epimedin I (1), a new chromone, 5, 7-dihydroxy-2-(p-hydroxy-phenoxy)-6-prenyl-chromone (2), and icariside A7 (3) were isolated from the aerial parts of Epimedium koreanum NAKAI (Berberidaceae) together with six known compounds, chaohuoside A (epimedin L) (4), 8-prenylkaempferol (5), anhydroicaritin (6), ginkgetin (7), isoginkgetin (8) and bilobetin (9). Their structures were established by spectroscopic methods and chemical evidence.
