【 摘 要 】

The yields and chemical compositions of the essentialoils obtained by steam distillation of the fresh and dried (30 and 40 ºC)leaves, stems and roots of Tanaecium nocturnum are reported. The identificationand quantification of the volatile constituents were accomplished by GC/MS andGC/FID, respectively. The essential oils obtained from the various parts ofthe plant were constituted mainly of benzaldehyde. Large losses and variationsin the quantities of the components during the drying process were observed.The presence of mandelonitrile in higher concentration in the stem and rootsindicates that this species produces cyanogenic glycosides.
