ABSTRACT
<p><b>AIM</b>To study the active constituents of Swertia davidi Franch.</p><p><b>METHODS</b>Column chromatographies on silica gel, Sephadex LH-20 and Diaion-201 et al. were used to isolate and purify the chemical components. Their structures were identified by UV, IR, MS, NMR and 2D-NMR.</p><p><b>RESULTS</b>These compounds were elucidated as 8-O-beta-D-glucopyranosyl-1, 3, 5-trihydroxyxanthone (I), 5-O-beta-D-glucopyranosyl-1, 8-dihydroxy-3-methoxyxanthone (II), 5-O-beta-D-glucopyranosyl-1, 3, 8-trihydroxyxanthone (III) and swertamarin (IV).</p><p><b>CONCLUSION</b>Compound III is a new xanthone glucoside. The other compounds were isolated from this plant for the first time.</p>
