摘　　要：以广佛手不同成熟期的鲜果为材料,采用顶空固相萃取及GC-MS法,分析其挥发性物质含量成分及变化。结果表明:从花后160～200 d的5个成熟期共鉴定出25种成分,各成熟期成分的种类、数量基本相同。挥发性物质成分以烯类为主,占含量的96%以上,其中又以柠檬烯和松油烯为主,分别占含量的44%和27%以上。这些主要成分的含量之和先上升后下降,在花后180 d达最高值,说明花后180 d应为佛手采收最佳期。In this study,fresh citrus bergamot fruits in 5 different mature periods were used for content analysis of volatile substances using headspace solid phase microextraction coupled to Gas Chromatograph-Mass Spectrometer（GC-MS）.No obvious differences of the component amount were found in different periods and total 25 components were identified.Terpenes,including isolimonene（accounting for more than 44%） and terpinene（more than 27%） and so on,are the main component amounting for more than 96%.Changes of the total contents display a rising first and then falling trend,and achieve the highest level 180 days post-flowering,when half of the fruit is yellow.These results showed that 180 days post-flowering might be the best time for citrus bergamot harvesting.
