Euphatexols C − G, five new triterpenoids from the latex of <i>Euphorbia resinifera</i>

Abstract

Five new triterpenoids named as euphatexols C - G (<b>1</b>-<b>5</b>) were isolated from the latex of <i>Euphorbia resinifera</i>. Their chemical structures were determined by extensive spectroscopic analysis, including IR, HRMS, 1 D and 2 D NMR data. Compounds <b>1-5</b> showed moderate anti-inflammatory activity with IC₅₀ values of 22.30, 48.04, 21.89, 38.15 and 41.15 μM, respectively.
