ABSTRACTESSENTIAL OILS IN VIETNAMESE CORIANDER LEAVES (Persicaria odorata),TORCH GINGER FLOWER(Etlingera elatior) AND GALANGAL(Alpinia galangal)Essential oil plants and culinary herbs include a broad range of plant species that are used fortheir aromatic value as flavoring in food, beverage, fragrance in pharmaceutical and industrialproducts. Vietnamese coriander leaves (Persicaria odorata) has triacethyl-alpha-terpeniol(eucalyptol or linalool) (73.52%) is the main component of the essential oil in this herb. Intorch ginger flower (Etlingera elatior), its main component is 2-methyl-2-propenaldiethylhydrazone (43.64%). While for the galangal (Alpinia galanga), the chemicalconstituents of this oil is cyclolongifolene oxide (31.72%). For this study, the essential oil ofVietnamese coriander leaves, torch ginger flower and galangal leaves were extracted by usinghydrodistillation method and the components of essential oil in the herbs are determined byusing gas chromatography-mass spectrometry.Ylll
