COMPARATIVE-STUDY OF COLOMBIAN RUE OILS BY HIGH-RESOLUTION GAS-CHROMATOGRAPHY USING DIFFERENT DETECTION SYSTEMS

Volatile secondary metabolites from different parts (flowers, leaves, stems, and roots) of Colombian rue (Ruta graveolens) were obtained by combined steam distillation-solvent extraction. The various oils were analyzed by means of GC using FID, NPD, or MSD. The chemical compositi on of the oils extracted from the aerial parts differed drastically fr om those extracted from the roots. 3-Pyrrolidinol, 1,4-dimethylpiperaz ine, and various 1,3-benzodioxole derivatives were detected in the Col umbian rue oil for the first time.
