A phoshphodiesterase-5 inhibitor, it is obtained from several species of plants in the genus Epimedium and is thought to be the main active ingredient of the Chinese herbal medicine Herba Epimedii (yinyanghuo). It has a role as a bone density conservation agent, a phytoestrogen, an EC 3.1.4.35 (3',5'-cyclic-GMP phosphodiesterase) inhibitor and an antioxidant. It is a glycosyloxyflavone and a member of flavonols."}]
