摘　　要：目的：研究不同采收期椪柑果皮挥发油成分动态变化规律。方法：采用水蒸气蒸馏法提取挥发油,GCMS进行分析鉴定;应用Kováts保留指数与质谱对化合物定性,面积归一化法定量。结果：6个时间点采集的椪柑果皮中共定性、定量68个化合物,总含量为94.27%~97.12%;6批椪柑果皮中含量最高的3个化合物分别是d-柠檬烯（56.862%~67.728%）、γ-萜品烯（9.298%~11.081%）、芳樟醇（4.792%~7.893%）;不同采收期椪柑果皮挥发油成分在物质种类上差异较小,8、9月采摘的椪柑果皮与后期采摘的相比在含量上有显著性差异。结论：不同采收期椪柑果皮挥发油成分动态变化呈现一定的规律性。Objective： To study the chemical variation of essential oils in peels collected from Citrus reticulata‘Ponkan＇in different time. Methods： The volatile oils were extracted by steam distillation and analyzed by GC-MS. The oil components were identified by their mass spectra and Kováts retention indices（ RIs） and quantified by the area normalization method. Results： A total of 68 compounds were identified in 6 samples harvested in different time,and the total contents of identified compounds in each sample were from 94. 27% to 97. 12%. The highest content compounds were d-limonene,γ-terpinene and linalool representing 56. 862% ~ 67. 728%, 9. 298% ~ 11. 081% and 4. 792% ~ 7. 893%,respectively. There was little difference in the chemical components between different samples,but a great variation in quantitation between the former 2 samples and the latter 4 samples. Conclusion： The chemical variability of essential oils from 6 Citrus reticulata‘Ponkan＇peel samples presents a regularity.
