Abstract

Objective:To study the chemical constituents of the leaves of E.serratifolia S.Moore.Method:Isolation and purification were carried out on the chromatography of silica gel and Sephadex LH-20.Their structures were elucidated on basis of physicochemical properties and spectral data.Result:Six compounds were isolated and identified asβ-sitosterol(Ⅰ),glycerol mono stearol acid(Ⅱ),oleanolic acid(Ⅲ),ursolic acid(Ⅳ),protocatechuic acid(Ⅴ),daucosterol(Ⅵ).Conclusion:Compounds Ⅰ~Ⅵ are isolated from this plant for the first time.
