Abstract
OBJECTIVE
To study the chemical constituents in bark of Dictamnus dasycarpus.
METHODS
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.
RESULTS
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).
CONCLUSIONS
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.
