卡南加油中挥发性成分的GC-TOFMS分析

Analysis of Volatile Components in Cananga Oil by GC-TOF MS

利用气相色谱-飞行时间质谱联用技术,对卡南加油的挥发性成分进行了分析,并用峰面积归一化法计算了各成分的含量。通过质谱库检索,结合保留指数法,分析并鉴定了卡南加油中的72个成分,占卡南加油挥发性成分的93.33%。卡南加油的主要成分为苯甲酸苄酯(18.359%)、α-芳樟醇(16.186%)、(E)-石竹烯(10.412%)、α-毕橙茄醇(5.651%)、δ-荜澄茄烯(5.241%)、乙酸香叶酯(3.247%)、γ-衣兰油烯(2.969%)等。其中,萜类化合物及其衍生物共57个,占卡南加油挥发性成分的72.33%。

The volatile components of cananga oil were analyzed by using of gas chromatography-time-of-flight mass spectrometry（ GC-TOF MS）. The peak area normalization method was used to calculate the content of each component. With the mass spectrometry library search,72 compounds which accounted for 93. 33% in the volatile components of cananga oil were identified by using MS database and retention index of ESO. The main componments were benzyl benzoate（ 18. 359%）,α-linalool（ 16. 186%）,trans-caryophyllene（ 10. 412%）,α-cadinol（ 5. 651%）,δ-cadinene（ 5. 241%）,geranyl acetate（ 3. 247%）,γ-muurolene（ 2. 969%）. Among 72 compounds,57 components were terpenoids and their derivatives,which account for 72. 33%in the volatile components of Cananga oil.
