摘要：采用全自动热脱附-气相色谱-质谱(ATD-GC-MS)联用技术,对动态顶空密闭循环吸附捕集的缅栀子花朵的挥发性成分进行分析检测,并用峰面积归一化法测定其相对含量。结果表明:在检出的77.31%的挥发性成分中,醛类含量最高约占29.5%,其次是醛的衍生物醛肟(24.99%),此外还有腈类(5.34%)、烷烃(3.68%)、芳香烃(1.42%)、醚类(4.64%)、萜烯类(6.67%)和醇类(1.67%);除醛类中有多种属香料成分外,柠檬烯(萜烯类)和苯乙醇(醇类)也具有特殊香气。
An automatic thermal desorption-gas chromatography-mass spectrometric（ATD-GC-MS） system was applied to analyze the volatile composition of the fresh flowers of Plumeria rubra Linn.cv.Acutifolia based on dynamic head-space closed cyclic adsorption sampling.The quantification of volatile compounds was carried out using area normalization method.The sum of the relative contents of identified volatile compounds in the fresh flowers of Plumeria rubra Linn.cv.Acutifolia was 77.31%,and among them,aldehydes were the most predominant group of compounds,with a relative content of 29.5%,followed by oximes（24.99%）,derivatives of aldehydes,and nitriles（5.34%）,alkanes（3.68%）,aromatic hydrocarbons（1.42%）,ethers（4.64%）,terpenes（6.67%） and alcohols（1.67%） were also included.Besides some of the identified aldehydes,the compounds responsible for the characteristic aroma of Plumeria rubra Linn.cv.Acutifolia flowers also consist of limonene belonging to the group of terpenes and phenyl ethanol belonging to the group of alcohols.
