摘　　要：采用吹扫捕集、气相色谱质谱和嗅辨仪联用法,对金桂鲜花的挥发性香气成分进行了富集和分析。研究表明芳樟醇和二氢-β-紫罗兰酮是构成金桂鲜花香气的主要组成成分,它们分别占香气成分总量的42.104%和16.689%。其次为异戊醇和橙花醇,分别占7.661%和4.993%。通过嗅辨仪辨香发现,对金桂鲜花香气特征起关键作用的成分按出峰时间先后依次为叶醇、异丁酸叶醇酯、芳樟醇氧化物、芳樟醇、脱氢芳樟醇、二氢-β-紫罗兰酮、橙花醇、茉莉酮、二氢-β-紫罗兰醇和γ-癸内酯,且这些成分各自表现的香气强度各不相同。The volatile aroma components from fresh flowers of Osmanthus fragrans were enriched and analyzed by purge and trap/GC-MS/olfactometer.The results showed that linalool and dihydro-β-ionone were identified as the dominant components in fresh flowers of osmanthus fragrans,and they accounted for 42.104%and 16.689%of total content,respectively,follwed by isoamylol and nerol which accounted for 7.661%and 4.993%,respectively.According to the order of peak time by olfactometer,the components that played key roles in the aroma characteristics of osmanthus fragrans were cis-3-hexen-1-ol,cis-3-hexenyl iso-butyrate,linalool oxide,linalool,hotrienol,dihydro-β-ionone,nerol,jasmone,dihydro-β-ionol andγ-decanolactone,and they showed different aroma intensity.
