| Abstract: | Objective To investigate the chemical constituents from Euphorbia latifolia.Methods The constituents of CHCl3-soluble portion of 95% ethanol extract were isolated and purified by repeated chromatographies with silica and Sephadex LH-20.Compounds were identified by their physical characteristics and spectral features.Results Eight compounds were isolated and identified respectively as lacceroic acid（1）,taraxasterol（2）,α-spinasterol（3）,lupeol（4）,β-sitosterol（5）,betulinic acid（6）,oleanolic acid（7） and betulin（8）.Conclusion Compounds 1-4 were isolated from this plant for the first time. |
