Abstract: 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.
