  The medicinal plant garden of Hoshi University located in southern Tokyo is home to many medicinal plants, and analysis of odor and measurement of antioxidant activity of cultivated plant have been carried out. In this study compounds originated from Curcuma rhizomes, i.e., Curcuma longa, Curcuma aromatica, Curcuma zedoaria, Curcuma xanthorrhiza, were investigated and antioxidant activities of rhizome extracts were measured. Volatile compounds originating from the Curcuma rhizomes were analyzed using thermal desorption (TD)-GC-MS with solid-phase micro extraction fiber as an adsorption device. p-Cymene, 1,8-cineol, β-elemene, and β-caryophyllene were the predominant constituents in most cases. Curcuminoids, which were not identified by TD-GC-MS, were detected using direct analysis in real time time-of-flight MS. Curcumin and demethoxycurcumi.. View More»
