Popis:	The solvent extract and the headspace of Hedychium coronarium Koenig flowers were investigated by GC and GC/MS. A volatile concentrate of the solvent extract which was obtained by simultaneous distillation and extraction (SDE) was fractionated by column chromatography and analyzed by GC and GC/MS. Of the 175 compounds identified, linalool, methyl benzoate, cis-jasmone, eugenol, (E)-isoeugenol, jasmin lactone, methyl jasmonate, methyl epi-jasmonate, indole, nitriles and oximes were found to make a great contribution to the scent of the flowers. Total of 113 compounds were identified in the headspace. The daily and the seasonal changes of the odor characteristics of H. coronarium flowers were considered. Qualitative differences of the volatiles obtained by thermal and solvent desorption of the headspace traps were also discussed.
