ABSTRACT
<p><b>OBJECTIVE</b>To study chemical constituents from Cynanchum auriculatum.</p><p><b>METHOD</b>The chemical components were isolated and purified by silca gel, sephedex-LH-20 and ODS column chromatography. The chemical structures were elucidated on the basis of physicochemical properties and spectral data.</p><p><b>RESULT</b>Thirteen compounds were isolated and identified as: caudatin (1), metaplexigenin (2), cynauricuoside A (3), succinic acid (4), azelaic acid (5), wilforibiose (6), sucrose (7), 1-O-hexadecanolenin (8), beta-amyrin acetate (9), cynanchone A (10), acetylquinol (11), beta-sitosterol (12), daucosterol (13).</p><p><b>CONCLUSION</b>Compounds 4-9 were obtained from this plant for the first time.</p>
