ABSTRACT
<p><b>OBJECTIVE</b>To investigate the chemical constituents of Oldenlandia diffusa.</p><p><b>METHOD</b>The column chromatography with polyamide Sephadex LH -20, silica gel as packing materials and HPLC, were used to separate and purify the chemical components. The structures were elucidated on the basis of physicochemical properties and spectral data.</p><p><b>RESULT</b>Nine compounds were isolated and identified as 2, 6-dihydroxy-1-methoxy-3-methylanthraquinone (1), 2-hydroxy-1-methoxy-3-methylanthraquinone (2), 2-hydroxy-3-methylanthraquinone (3), quercetin-3-O-[2-O-(6-O-E-sinapoyl)-beta-D-glucopyranosyl]-beta-glucopyranoside (4), quercetin-3-O-[2-O-(6-O-E-feruloyl)-beta-D-glucopyranosyl]-beta-glucopyranoside (5), kaempferol-3-O-[2-O-(6-O-E-feruloyl)-beta-D-glucopyranosyl]-beta-galactopyranoside (6), quercetin-3-O-(2-O-beta-D-glucop-yranosyl)-beta-D-glucopyranoside (7), rutin (8) and quercertin (9).</p><p><b>CONCLUSION</b>Compounds 1 and 8 were obtained from this plant for the first time, and compound 1 was a new compound.</p>
