Epimedin B is a glycoside and a member of flavonoids. Epimedin B is a natural product found in Epimedium pubescens, Epimedium grandiflorum, and other organisms with data available. Epimedin B, a component extracted from Epimedii Folium, is reported to have antiosteoporotic activity. IC50 value: Target: In vitro: In vivo: Prednisolone-induced osteoporosis model using zebrafish was used to evaluate the antiosteoporotic activity of micro amount epimedin B. The result showed that 1 μmol·L- 1epimedin B groups were significantly increased when compared with model group; Epimedin B can prevent zebrafish osteoporosis induced by prednisolone [1].
