Abstract:ObjectiveTo study the fat-soluble chemical constituents of Carex siderosticta.MethodsThe column chromatography was used for isolation of chemical constituents.The chemical constituents was separated and identified by physiochemical and spectroscopic analysis.ResultsEleven compounds were isolated from 70% ethanol extract of Carex siderosticta and four of them were identified as dotriacontan (Ⅰ), lacceroi cacid (Ⅱ), β-sitosterol(Ⅲ),β- daucosterol (Ⅳ).ConclusionAmong these compounds Ⅰ-Ⅳ were obtained from sedge family for the first time.
