ABSTRACT
<p><b>OBJECTIVE</b>To study the chemical constituents of Oxytropis falcate.</p><p><b>METHOD</b>The air-dried whole plants of O. falcate were extracted with EtOH (90%) three times at room temperature. The compounds were isolated by silica-gel, polyamide, C-18 and Sphadex LH-20 columns. The structures were identified based on spectral elucidation.</p><p><b>RESULT</b>Fourteen compounds were isolated from O. falcate and identified as, (-)-7-methoxy-dihydroflavone (1), (-)-5-hydroxy-7-methyoxy-dihydroflavone (2), (-)-pinocembrin (3), (-)-7-hydroxy-dihydroflavone (4), 4'-methoxy-2'-hydroxy-chalcone (5), 2', 4'-dihydroxy-dihydrochalcone (6), 2',4'-dihydroxy-chalcone (7), (-)-maackiain (8), tetrahydroflemichapparin-B (9), dalbergin (10), N-benzoyl-2-phenylethylamine (11), n-tetracosanol (12), rhamnocitrin-3-O-beta-neohesperidoside (13), beta-sitosterol (14).</p><p><b>CONCLUSION</b>All the compounds were isolated from O. falcate for the first time.</p>
