ABSTRACT
<p><b>OBJECTIVE</b>To determine the chemical constituents of Gentiana rhodantha.</p><p><b>METHOD</b>To isolate the constituents, column chromatography over silica gel, MCI, Sephadex LH-20 and C18 reverse-phased silica gel were used. Spectroscopic methods were used to elucidate the structures of the isolated compounds.</p><p><b>RESULT</b>Sixteen compounds were isolated and elucidated as ten phonemic compounds, namely 1,3,7,8-tetrahydroxylxanthone (1), rhodanthenone D (2), 1,3,6,7-tetrahydroxylxanthone (3), 1,3,7-trihydroxy-4,8-dimethoxyxanthone (4), quercetin (5), isoorientin (6), mangiferin (7), norswertianolin (8), gallic acid ethyl ester (9) and salicylic acid (10), and six triterpenes including alpha-amyrin (11), erythrodiol 3-O-palmitate (12), ursolic aldehyde (13), uvaol 3-O-acetyl (14), ursolic acid (15) and 2alpha-hydroxyursolic acid (16).</p><p><b>CONCLUSION</b>Compounds 4-6, 8, 10-12, 15 and 16 were isolated from this plant for the first time. Compounds 1 and 3 were obtained firstly from the genus Gentiana and compounds 9, 13-14 were firstly from the family Gentianaceae.</p>
