ABSTRACT

<p><b>OBJECTIVE</b>To study the chemical constituents in bark of Dictamnus dasycarpus.</p><p><b>METHOD</b>Isolation and purification were carried out on silica gel column chromatography, prepared thin layer chromatography and sephadex LH - 20, et al. The structures were identified by spectral analysis.</p><p><b>RESULT</b>Twelve compounds were obtained from bark of D. dasycarpus and the structures were determined as dictamnine (I), fraxinellone (II), skimmianine (III), gamma-fagarine (IV ), beta-sitosterol (V), obacunone (VI), limonin disophenol (VII), fraxinellonone (VIII), wogonin (IX), rutevin (X), kihadinin B (XI), dasycarine (XII).</p><p><b>CONCLUSION</b>Compounds IX and XI were isolated from genus Dictamnus for the first time, and compound VIII was isolated from the species for the first time.</p>
