Abstract
A variety of chromatographic methods were applied to research the chemical composition of the roots of Euphorbia ebracteolata. Meanwhile, the structures of these compounds were identified by spectroscopic data, such as 1D, 2D NMR and HR-ESI-MS. In the present research, a new phenolic acid compound, 1,3,4,5-tetrahydroxy-2-O-β-D-[(6'-Gallic acyl)-glucopyranyl] isopentane(1), was isolated from the roots of E. ebracteolata, as well as three known compounds, isopropyl-2-O-β-D-(6'-gallic acyl)-glucopyranoside(2), ellagic acid(3) and 3,4'-di-O-methylellagic acid(4) respectively. Additionally, compounds 2 and 4 were isolated from the Euphorbia genus for the first time.
