ABSTRACT
<p><b>OBJECTIVE</b>To study the chemical constituents of the root of Hemerocallis fulva.</p><p><b>METHOD</b>Compounds were isolated by repeated silica gel, Sephadex LH-20, MCI gel, etc. column chromatography and their structures were determined by spectral analyses and physicochemical properties.</p><p><b>RESULT</b>From the n-butanol fraction of the EtOH extract of the roots of H. fulva, 9 glycosides were isolated and identified as sweroside (1), laganin (2), picraquassioside C (3), puerarin (4), 3'-methoxypuerarin (5), 7-hydro xylnaphthalide-O-beta-D-glucopyranoside (6), orcinol-3-O-beta-glucopyranoside (7), HN saponin F (8), hederagenin-3-0-beta D-glucopyranosyl-(1-3)-alpha-L-arabinopyranoside-28-O-beta-D-glucopyranosyl ester (9).</p><p><b>CONCLUSION</b>Compounds 1-9 were isolated from the genus Hemerocallis for the first time.</p>
