不同品种鲜桂花所散发的顶空成分。采用顶空固相微萃取(HS-SPME) -气相色谱/质谱联用（GC/MS）对花进行了研究。本研究共鉴定出20种挥发物，13种挥发物，9种挥发物。(Z)-辛烯、4-己烯乙酸酯、顺式芳樟醇氧化物、反式芳樟醇氧化物、β-芳樟醇、α-离子酮、β-离子酮、γ-癸内酯是三种桂花鲜花释放的相同挥发物。通过相似度评价和主成分分析对指纹进行化学模式识别。结果表明，顶空固相萃取-气相色谱/质谱法为不同品种鲜桂花中主要挥发性香气的鉴别提供了一种简便的取样方法。花既有相似之处，又有不同之处。不同品种的新鲜桂花有不同的香味。利用指纹相似度评价和主成分分析对花进行了分类。
The headspace constituents emitted from different varieties of fresh Osmanthus fragrans Lour.flowers were investigated by means of headspace solid-phase microextraction(HS-SPME)coupled to gas chromatography/mass spectrometry(GC/MS).In this study 20 volatile compounds were identified in Osmanthus fragrans var.thunbergii,13 volatile compounds were identified in Osmanthus fragrans,9 volatile compounds were identified in Osmanthus fragrans f.aurantiacus.(Z)-ocimene,4-hexenyl acetate,cis-linalool oxide,trans-linalool oxide,β-linalool,α-ionone,β-ionone,γ-decalactone were the same volatiles released from fresh flowers of three different Osmanthus fragrans Lour.The fingerprints were analyzed by similarity evaluation and principle component analysis to conduct the chemical pattern recognition.The results indicated that headspace SPME-GC/MS afforded a simple sampling method for identification of the main volatile fragrance from different varieties of fresh Osmanthus fragrans Lour.flowers.The fragrans of Osmanthus fragrans Lour.flowers not only had some resemblance,but also had some difference.The different varieties of fresh Osmanthus fragrans Lour.flowers were distinguished and classified by fingerprints similarity evaluation and principle component analysis.
