Abstract:
Objective To study the chemical constituents of Epimedium sutchuenense.Methods The compounds were repeatedly separated and purified on column chromatography of silica gel,polyamide,Sephadex LH-20,and ODS.The structures were identified on the basis of spectral methods.Results Ten compounds were isolated from 70% ethanol extract of E.sutchuenense and were identified as sutchuenoside A(Ⅰ),sutchuenoside B(Ⅱ),daidzein(Ⅲ),baohuoside-Ⅰ(Ⅳ),kaempferide 3-rhamnoside(Ⅴ),icariin(Ⅵ),anhydroicaritin-3-O-?-L-rhamnopyranosyl(1→2)-?-L-rhamnopyranoside(Ⅶ),p-hydroxybenzoic acid(Ⅷ),daucosterol(Ⅸ),and ?-sitosterol(Ⅹ),respectively.Conclusion Compounds Ⅰ and Ⅱ are novel ones named as sutchuentins A and B respectively.Compounds Ⅲ,Ⅴ,Ⅶ,and Ⅷ-Ⅹ are isolated from this plant for the first time.
