Studies on the chemical constituents of ethyl acetate extract from the roots of Actinidia chrysantha

Objective:To study the chemical constituents of ethyl acetate extract from the roots of Actinidia chrysantha.Methods: Chromatographic methods were used to isolate the compounds from ethyl acetate extract from the roots of Actinidia chrysantha and chemical and spectral methods were used to elucidate the structures of the isolated compounds.Results: Five compounds were identified as stigmast-3,6-dione(Ⅰ),β-sitosterol(Ⅱ),ursolicacid(Ⅲ),β-daucosterol(Ⅳ),2α,3β,23-triol-12-en-28-ursolic acid(Ⅴ).Conclusion: Those compounds are obtained from the plant for the first time.
