left until the petal turned to yellow color which producing the fragrance before placed into glass bottom (100 ml) and then closed with rubber cap. The stableFlex SPME fiber was inserted into bottom for 30 min. Afterward, the absorbed volatiles on SPME were inverstigated by gas chromatography-mass spectrometry (GC-MS) Agilent 6850/HP 5975 equipped a fused silica capillary column (HP-5MS). The oven temperature was stepwise programmed from 50ºC to 260ºC. The spectra analysis was operated in the electron impact (El) mode with and electron energy of 70 ev; mass range (m/z) 30-500 and EM voltage 3000 V. Volatile components were identified using the ChemStation program with NIST 98 library.
