ABSTRACT
<p><b>OBJECTIVE</b>To in vestigate the constituents in root of Gentiana macrophylla.</p><p><b>METHOD</b>Various column chromatographic techniques were used for isolation and purification of the principles. The structures were elucidated on the basis of spectral data (UV, IR, MS, 1H-, 13C-NMR etc.) and identified by comparing with standard substance.</p><p><b>RESULT</b>Eight compounds were identified. Four compounds isolated from the chloroform fraction are 5-carboxyl-3,4-dihydrogen-1H-2-benzopyran-1-one (1), erythrocentauric acid (2), roburic acid (3), oleanolic acid (4). Water fraction gave four known secoiridoid glucosides. They were gentiopicroside (5), swertiamarine (6), sweroside (7), 6'-O-beta-D-glucosylgentiopicroside (8).</p><p><b>CONCLUSION</b>1 is a novel compound. It was named as erythrocentauric acid. 2 was isolated from genus Gentiana and 8 was isolated from G. macrophylla for the first time.</p>
