Abstract:
Fragrance constituents released from fresh flowers of Edgeworthia chrysantha Lindl.were investigated by gas chromatography-mass spectrometry.The volatiles were sampled by solid phase microextraction(SPME).SPME sampling was conducted with 30 μm PDMS fiber at (25±5)℃ for 30 min.The fibers were desorbed in a GC injection liner at 250℃ for 5 min.A capillary column(WCOT FUSED SILICA 30 m×0.25 mm ID COATING CP-SIL 8 (CB-LOW) BLEED/MS DF=0.25 μm) was employed in GC-MS analysis.Initial oven temperature was kept at 40℃ for 5 min,then raised to 250℃ at 3℃/min,and kept at 250℃ for 5 min.Chemical constituents were separated and identified by GC-MS.γ-Terpinene(56.41%),benzyl acetate(10.77%),2-phenyl ethyl acetate(9.58%),(3,7-dimethyl-2),6-octadien-1-ol,acetate(5.61%),methyl salicylate(3.91%),methyl benzoate(2.85%),trans-(ocimene)(1.80%),benzaldehyde(1.75%)and 3-decen-2-one,3-methyl(1.40%)were the most abundant volatiles released from fresh flowers of E. chrysantha,and a total of 30 volatile compounds were identified in this study.(SPME-GC-MS) afforded a feasible and simple method for analyzing volatiles released from fresh flowers.
