| 摘 要： | 采用固相微萃取（SPME）技术和气相色谱与质谱联用法（GC—MS）对龙眼果皮中的挥发性化学成分进行分析、鉴定。结果表明，从龙眼果皮中共检测、鉴定出25种成分，占总挥发性化学成分的99．21％，主要成分是酯类、甾醇类、萜类烷烃和酮类化合物。其中，羟基洋地黄毒苷元含量最高，占47．59％；其次是苍耳酯，占22．92％。

| Abstract: | Gas chromatography-mass spectrometry combined with solid-phase microextraction （SPME-GC-MS） was developed for the determination of volatile constituents of longan periearp. The volatile constituents of longan periearp were extracted by SPME with a 100 μm polydimethylsiloxane fiber. The fibers were desorbed in a GC injection liner at 250 ℃ for 3 min. With headspaee SPME- GC-MS analysis, in longan periearp 25 constituents were identified by mass spec-trometry. The principal components were gltoxigenin （47.59%）, xanthumin （22.92%）, eolumbin （7.76%）, 1 ; 1＇- 3-（3-eyelopentylpropyl）-1,5-pentanediyl] bis-（6.21% ）, resibufogenin （ 3.39% ）. |
