Chemical constituents of Castanea mollissima

Objective To isolate and identify the compounds from the EtOAc fraction of 90% EtOH extract of seeds of Castanea mollissima Blume.Methods Compounds were isolated by the silica gel and Sephadex LH-20 columns and their structures were identified by the physicochemical characters and spectral analysis.Results Seven compounds were obtained and identified as uracil(1),n-butyl-β-fructopyranoside(2),azelaic acid(3),isoenanthic acid(4),sucrose(5),β-sitosterol(6),daucosterol(7).Conclusions Compounds 1-4 are obtained from Cstanea genus for the first time.
