中文摘要：
以云南德宏地区栽培的不同柠檬品种为试材，利用气质联用技术（GC-MS）分析果皮精油挥发性成分种类及相对含量，比较不同品种挥发性成分差异。结果表明，费米耐劳、云柠1号、艾伦尤力克柠檬果皮精油中分别检测到23、20、27种挥发性成分，烯烃类、醇类、醛类、酯类和酮类是3个品种共有组分。烯烃类物质是主要组分，其中特征香气成分D-柠檬烯含量最高，β-蒎烯、γ-萜品烯次之。艾伦尤力克柠檬中挥发性物质的种类和含量均高于费米耐劳和云柠1号柠檬，主要特征香气成分含量也最高。
英文摘要：
The volatile components of the peel of different lemon cultivars obtained from Dehong （Yunnan Province, China） were analyzed using GC-MS. The components and relative contents were compared.The results indicated that, total 23, 20 and 27 components were detected from Femminello, YN ＂1＂ and Allen Eureka, respectively. Hydrocarbon, aldehydes, alcohols, esters and ketones were common volatile components of 3 lemon cultivars.Different types of alkenes are the main compoments of lemon fruit, in which the major characteristic aromatic component are limonene, followed by β-Pinene and y-Terpinene.The volatile components of contents and categories detected in Allen Eureka were found to be higher than Femminello and YN＂I＂.
