ABSTRACT
<p><b>OBJECTIVE</b>To study the chemical constituents of the roots of Osbeckia opipara.</p><p><b>METHOD</b>Repeated column chromatography over silica gel, RP-18 and Sephadex LH-20, and preparative thin layer chromatography(PTLC) were used to isolate the compounds, whose structures were determined by spectroscopic methods by direct comparing spectral data with those reported references.</p><p><b>RESULT</b>From the MeOH extract of the roots O. opipara, twelve compounds were isolated and identified as follows lasiodiplodin (1) , de-O-methyllasiodiplodin (2), 2, 3- dihydro-2-hydroxy-2, 4-dimethyl-5-trans-propenylfuran-3-one (3), integracin (4), 5alpha, 8alpha-epidioxy-(22E, 24R)-ergosta-6, 22-dien-3beta-ol (5), 3, 3', 4'-tri-O-methylellagic acid (6), 5-hydroxymethyl furaldehyde (7), vomifolio (8) , betulintic acid (9), 2alpha-hydroxyursolic acid (10), (24R)-stigmast-4-ene-3-one (11), and eugenitin (12).</p><p><b>CONCLUSION</b>Compounds 1-12 were isolated from O. opipara for the first time.</p>
