ABSTRACT
<p><b>OBJECTIVE</b>To study the chemical constituents of the roots of Euphorbia soongarica (Xinjiang origin).</p><p><b>METHOD</b>Compounds were isolated and purified by repeated normal column chromatography, preparative thin layer chromatography and Sephadex LH - 20 chromatography. The chemical structures were elucidated by NMR and MS spectra.</p><p><b>RESULTS</b>Ten chemical constituents were isolated from the n-BuOH fraction and identified as ellagic acid (1) , 3, 3'-di-O-methylellagic acid (2) , 3, 3'-di-O-methylellagic acid-4'-O-alpha-D-arabinfuranoside (3), 3, 3'-di-O-methylellagic acid-4'-O-beta-D-xylopyranoside (4), 3, 3'-di-O-methylellagic acid-4-O-beta-D-glucopyranoside (5), 3, 3', 4'-tri-O-methylellagic acid (6), 3-O-methylellagic acid-4'-O-beta-D-xylopyranoside (7), 3, 3', 4-tri-O-methylellagic acid-4'-O-beta-D-glucopyranoside (8), brevifolin (9) and ethyl brevifolin carboxylate (10).</p><p><b>CONCLUSION</b>All of above compounds were obtained from this plant for the first time.</p>
