8个不同柠檬品种果皮香气成分的GC-MS分析

采用水蒸气蒸馏提取法并结合气相色谱-质谱联用(GC-MS)技术对柠檬8个品种果皮香气成分进行了检测和分析。结果显示,从‘阿伦’、‘尤力克’、‘费米耐劳’、‘斐诺’、‘库托迪肯’、‘蒙纳盖洛’、‘维尔纳’、‘维拉弗兰卡’8个品种果皮中分别鉴定出31、31、33、34、32、33、32和32种主要成分,分别占总峰面积的90.94%、93.42%、91.61%、91.02%、89.58%、88.11%、92.57%和92.09%;柠檬8个品种中共有成分24种,其中含量较高的有D-柠檬烯、α-松油醇、γ-松油烯、β-蒎烯、松油烯-4-醇等;柠檬8个品种所含成分种类、相对含量间存在差异,可作为区分这8个品种的重要特征。本研究结果可为柠檬果皮的综合利用及品种选育提供理论依据。

Analysis of Aromatic Components from the Peels of Eight Lemon Varieties by GC-MS

We detected and analyzed the aromatic components of the peels from eight lemon varieties using steam distillation extraction coupled with gas chromatography-mass spectrometry (GC-MS). Results showed that 31, 31, 33, 34, 32, 33, 32, and 32 main compounds were identified in the peels of‘Allen’,‘Eureka’,‘Feminello’,‘Fino’,‘Kwtdichen’,‘Monachella’,‘Verna’, and‘Villafranca’ lemons, amounting to 90.94%, 93.42%, 91.61%, 91.02%, 89.58%, 88.11%, 92.57% and 92.09% of total peak areas, respectively. Eight lemons contained twenty-four common components, including D-limonene, α-terpineol, γ-terpinene, β-pinene, and terpinen-4-ol. There were some differences in component types and percentage contents of the eight lemons, which could be used as important features to distinguish varieties. This study provides a theoretical basis for the integrated utilization of lemon peels and selection of lemon varieties.
