Abstract:
OBJECTIVETo study the chemical constituents in bark of Dictamnus dasycarpus.
METHODIsolation 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.
RESULTTwelve 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).
CONCLUSIONCompounds IX and XI were isolated from genus Dictamnus for the first time, and compound VIII was isolated from the species for the first time.
