| Abstract: | Objective To study the chemical constituents of euphorbium (resinous secretions of Euphorbia resinifera). Methods The chemical constituents were isolated and purified by chromatography with RP-18, silica gel, Sephadex LH-20 and preparative HPLC, and their structures were identified by analysis of spectroscopic data (IR, UV, HRESIMS, 1D and 2D NMR) and relevant references. Results Two compounds were isolated from the methanol extract of euphorbium, and they were identified as eupha-8-ene-3,25-diol-24-chloro-7-one (1) and 22,23,24,25,26,27-sexnoreupha-8-ene-20-ol-3,7-dione (2). Conclusion Compound 1 is a new triterpene, and compound 2 is a new nortriterpene isolated from euphorbium, named euphoritriol A and euphoritriol B, resepectively. |
