Résumé
The combination of normal-phase silica gel column chromatography, octadecyl silica(ODS) column chromatography, semi-preparative high performance liquid chromatography(HPLC), etc. was employed to isolate and purify the chemical components from Euphorbia resinifera, and 7 triterpenoids were separated from the ethanol extract of the medicinal materials. Their structures were identified by various spectroscopy methods as cycloartan-1,24-diene-3-one(1), cycloartan-1,24-diene-3-ol(2), 3β-hydroxy-lanosta-8,24-diene-11-one(3), lnonotusane C(4), eupha-8,24-diene-3β-ol-7,11-dione(5), eupha-24-methylene-8-ene-3β-ol-7,11-dione(6), and eupha-8,24-diene-3β,11β-diol-7-one(7). Compounds 1 and 2 are new compounds, and compound 3 is obtained from nature for the first time.
