Résumé
<p><b>OBJECTIVE</b>To study the chemical constituents from the root of Hedysarum multijugum.</p><p><b>METHOD</b>The compounds were separated by chromatographic methods, their structures were identified by spectral analysis.</p><p><b>RESULT</b>Four compounds were isolated and identified as soyasaponin II methyl ester (1), soyasaponin II (2), soyasaponin Bg (3), and soyasaponin I (4).</p><p><b>CONCLUSION</b>The four compounds were obtained from the plant for the first time. Compound 3 was isolated from the genus Hedysarum for the first time, and the NMR data of 3 was reported for the first time.</p>
