采用顶空固相微萃取结合气质联用仪分析香柚皮中的挥发性组分,并运用正交实验设计优化实验条件,考察了萃取头、萃取时间、萃取温度3个因素对固相微萃取分析结果的影响,得到了较优的实验条件。通过GC-MS进行定性定量分析,共鉴定出55种组分,主要挥发性组分为D-柠檬烯(80.37%)、圆柚酮(6.07%)、β-蒎烯(1.99%)、佛术烯(1.40%),占总质量分数的99.45%。

The volatile constituents was analyzed by combining Headspace Solid Phase Microextraction( HSSPME) and gas chromatography mass spectrometry( GC-MS),The effect of different SPME fibers,extraction time and extraction temperature on the analysis result were investigated by using orthogonal experimental design. Based on the analysis of Gaschromatography- Mass Spectrometry( GC- MS),The 59 volatile flavor components were separated and identified,and the main volatile components were D-Limonene( 80. 37%),Nootkatone( 6. 07%),β-Pinene( 1. 99%),Eremophilene( 1.40%) which were comprised 99.45% of the total peak areas.
