【摘要】 采用活体植株动态顶空套袋采集法与TCT-GC/MS联用分析技术相结合,采集分析了杭州满陇桂雨公园4个不同桂花品种的香气组分,通过与周围空气对照的比较,确定氧化芳樟醇、芳樟醇、β-紫罗兰酮、2H-β-紫罗兰酮、α-紫罗兰酮、香叶醇、罗勒烯等为桂花香气的主要挥发性有机成分;但不同桂花品种群的品种之间释放的挥发物在组分和相对含量上都存在差异。四季桂品种群的‘佛顶珠’含芳樟醇和β-紫罗兰酮较高,检测不到香叶醇;银桂品种群的‘玉玲珑’桂中含β-紫罗兰酮和顺式氧化芳樟醇较高;金桂品种群的‘小叶金’桂中含较多的芳樟醇、罗勒烯和β-紫罗兰酮;丹桂品种群的‘朱砂丹’桂中含较多的芳樟醇、氧化芳樟醇和反式香叶醇。更多还原

【Abstract】 Linalool oxide,linalool,β-ionone,dihydro-β-ionone, α-ionone,geraniol,ocimene,etc.were examined by dynamic headspace collection and TCT-GC/MS analysis from 4 Osmanthus fragrance cultivars in Hangzhou Manlong Guiyu Park,comparing with the surrounding air(CK).The results of comparing the volatile compounds in this 4 cultivars showed that there were some differences not only in their relative contents but also in the component’s content.There are more content of linalool and ionone in Osmanthus fragrans’Fo Ding Zhu’,but no geraniol can be detected.Osmanthus fragrans’Yu Linglong’contains more ionone and cis-linalool oxide.More linalool,ocimene and ionone were detected in Osmanthus fragrans’Xiaoye Jin’.Osmanthus fragrans’Zhusha Dan’contains more content of linalool,linalool oxide and trans-geraniol.更多还原
