| 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。

| Abstract: | 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. |
