摘　　要：采用固相微萃取(SPME)吸附采集白丁香鲜花的挥发性成分,并用GC-MS及总离子流色谱法定量分析了白丁香鲜花的挥发性成分,鉴定出丁香醛A^D、丁香醇A^D、α-蒎烯、桧烯、β-蒎烯、月桂烯、柠檬烯、桉树脑、顺式罗勒烯、苯甲醛、异松油烯、芳樟醇、苯乙醛、α-松油醇、对甲氧基茴香醚、茴香醛、(Z,E)-α-金合欢烯、(E,E)-α-金合欢烯等39种化合物。其中所含的4个丁香醇异构体和4个丁香醛异构体是白丁香鲜花的特征性香气成分,并考察了白丁香在不同开花期挥发性香气成分的变化。SPME-GC-MS是一种可用于分析不同开花期的鲜花香气成分变化的简单可行的分析方法。The chemical constituents of fragrance released from fresh flowers of Syringa oblata var. affinis were investigated by means of headspace solid-phase microextraction （SPME） coupled with gas chromatography-mass spectrometry （GC-MS）. Lilac aldehyde A- D, lilac alcohol A -D, α-pinene, sabinene, β-pinene, myrcene, D-limonene, eucalyptol, cis-ocimene, benzaldehyde, terpinolene, linalool, benzeneacetaldehyde, α-terpineol, p-methoxyanisole, p-anisaldehyde, （Z,E）-α-farnesene and （E, E）-α-farnesene were the most abundant volatiles released from fresh flowers of S. oblata var. affinis and 39 volatile compounds were identified in this study. The four isomers of lilac alcohol and four isomeric lilac aldehydes were the characteristic components of fragrance of fresh flowers of S. oblata var. affinis. Variation of the main constituents in the volatile fragrance from fresh flowers of S. oblata var. affinis during different florescences were also studied. Headspace SPME-GC-MS is a simple sampling method for measuring the variations of main constituents in volatile fragrance from fresh flowers during different florescence.
