the composition of the main constituents from different plant parts (rhizome, stems, leaves and flowers) of cultivated hedychium coronarium koenig, and the enantiomeric ratio of some of these, were determined by gas chromatography, chiral gas chromatography and gas chromatography/mass spectrometry. the number of components identified in the essential oils of rhizome, stems and leaves was twenty-three, fifteen and twenty-three, respectively, representing 98.8%, 97.7% and 98.9% of each corresponding oil. the major constituents in rhizome, stems and leaves oils included -pinene (9.6%, 10.0% and 23.0%), -pinene (39.1%, 38.8% and 44.1%), 1,8-cineole (32.2%, 5.6% and 5.1%) and -terpineol (4.9%, 12.2% and 0.2%), while (e)--ocimene, linalool and 1,8-cineole were identified in the flower aroma when exposed to solid-phase microextraction fibers. in addition, the chiral examination showed a high enantiomeric excess (ca. 99%) for (3r)-(-)-linalool in rhizome and flowers, (4s)-(-)--terpineol in leaves and (1s)-(-)-borneol in stems.
