Fragrances originating from plants are widely believed to have therapeutic properties. The volatile compounds originating from Curcuma longa (turmeric) plant cultivated in a medicinal plant garden located in southern Tokyo were investigated using thermal desorption-gas chromatography-mass spectrometry. Sampling from rhizomes of C. longa was performed at three different development stages, i.e., July (when young rhizomes emerge), September (flowers bloom), and November (ready for harvest). Using a polydimethylsiloxane (PDMS)-coated bar as an adsorption device for volatile compounds, 1,8-cineol, α-terpinolene, β-caryophyllene, and ar-curcumene were the predominant constituents in most cases. Additional volatile compounds such as α-terpinene, p-cymene, and (E)-β- farnesene were identified when PDMS/carboxene/divinylbenzene-coated fiber was used. ar-Turmerone was fou.. View More»
