摘要
采用顶空固相微萃取(HS-SPME)技术,采集桂花中四季桂、丹桂、银桂和金桂4个品种群的8个品种盛花期的香气成分,利用气相色谱质谱(GC-MS)联用仪进行分析鉴定,对GC-MS总离子色谱进行定量分析。四季桂、金桂和丹桂品种群的每个桂花品种都鉴定出了39种芳香成分,银桂品种群鉴定出了38种成分。4个品种群的桂花品种挥发油都含有罗勒烯、3-蒈烯、反式芳樟醇氧化物、顺式芳樟醇化合物、芳樟醇、壬醛、β-紫罗酮、α-紫罗酮和γ-癸内酯等9种化合物。结果表明,4个品种群的桂花芳香成分不存在根本性的差异。
A headspace solid-phase mieroextraction （HS-SPME） method was used to extract the essential oil of 8 Osmanthus fragrans cultivars from the 4 groups, which were then analyzed by gas chromatography-mass spectrometry （GC-MS） at full flowering stage. In this study, 39 volatile compounds were identified in each cultivar of asiaticus group, aurantiacus group and luteus group and 38 vola- tile compounds were identified in each one of albus group. Nine same components of the essential oil extracted from the 8 cultivars were ocimene, 3-carene, cis-linalool oxide, trans-linalool oxide, linalool, nonanal, β-ionone, α-ionone and ,γ-decalactone. The results suggested that the diffsrences of volatile compounds among O. fragrans cultivars were not obvious.
