ABSTRACT
<p><b>OBJECTIVE</b>To study the chemical constituents of Swertia macrosperma.</p><p><b>METHOD</b>The air-dried whole plants of Swertia macrosperma were extracted with boiling water. The extract was concentrated to a small amount of volume and extracted with petroleum ether, EtOAc and n-BuOH, successively. The compounds were isolated and purified by column chromatography from the EtOAc fraction, and identified based on spectral analyses (MS, 1H-NMR, 13C-NMR).</p><p><b>RESULT</b>Thirteen compounds were isolated from S. macrosperma, and were characterized as norbellidifolin (1), 1-hydroxy-3,7, 8-trimethoxy-xanthone (2), norswertianolin (3), swertianolin (4), 1,3,7,8-tetrahydroxyxanthone-8-O-beta-D-glucopyranoside (5), swertiamatin (6), decentapicrin (7), coniferl aldehyde (8), sinapaldehyde (9), balanophonin (10), together with beta-sitosterol, daucosterol, and oleanolic acid .</p><p><b>CONCLUSION</b>Compounds 2, 4-10 were obtained from Swertia macrosperma for the first time.</p>
