ABSTRACT
<p><b>OBJECTIVE</b>To investigate chemical constituents of the root bark of Tripterygium hypoglaucum.</p><p><b>METHOD</b>Compounds were isolated by column chromatography on silica gel and Sephadex LH-20, and their structures were identified on the basis of spectral data (MS, 1H-NMR and 13C-NMR).</p><p><b>RESULT</b>Twelve compounds were isolated and identified as friedelin (1), 3-oxo-olean-9(11),12-diene (2), canophyllal (3), 3-acetoxy oleanolic acid (4), triptophenolide (5), triptonoterpene methyl ether (6), tricosanoic acid (7), beta-sitosterol (8), stearic acid (9), glut-5-en-3beta,28-diol (10), palmitic acid (11) and daucostorol (12).</p><p><b>CONCLUSION</b>Compounds 1, 2, 3, 7 and 10 were isolated from T. hypoglaucum and 7 from the genus Tripterygium for the first time.</p>
