| 【目的】了解不同品种蜜柚柚花的香气成分差异，为柚花的加工利用提供参考。【方法】采用固相微萃取结合气相色谱-质谱联用分析法，对各成分质谱通过计算机谱库检索和资料分析，鉴定与比较分析了白肉蜜柚、红肉蜜柚、三红蜜柚、黄金蜜柚4种柚花的香气成分。【结果】从柚花中共检测出36种香气成分，4个品种柚花中分别为17、19、23、17种。柚花中香气成分主要均为芳樟醇，其中白肉蜜柚柚花中芳樟醇相对含量最高，达到68.65%，黄金蜜柚柚花含量次之，为67.43%，而红肉蜜柚和三红蜜柚柚花中芳樟醇含量相当，分别为65.01%和64.50%。三红蜜柚花朵的香气组成物质与其他三种比较，区别较大，萜烯类物质丰富，而酯类和烷烃类物质则较少。总之，本文初步从香气成分种类差异、共有香气成分相对含量差异以及各自特有成分上解释了4种柚花香气的区别，并分析和展望了柚花的应用前景。 |

| The objective of this study is to the difference of aroma components in different varieties of pomelo flower, and then provide reference for the processing and utilization of pomelo flower. he aroma components of four kinds of pomelo flowers were identified and analyzed by solid-phase microextraction combined with gas chromatography-mass spectrometry (GC-MS). Thirty-six kinds of aroma compounds were detected from the pomelo flowers, 17,19,23 and 17 kinds from four kinds of pomelo flowers respectively. Linalool is the mainly aroma component in pomelo flowers, the relative content of which in four flowers are 68.65%, 65.01%, 64.50% and 67.43%. The aroma components of the three red honey pomelo flowers are quite different from that in other three. There are rich terpenes and less esters and wlkanes.
