摘要: 以五个荔枝品种为试材,采用SPME/GC-MS方法对其香气成分进行了分析鉴定。结果表明,不同品种荔枝在香气组成和含量上差异显著,妃子笑、黑叶、白蜡、荔枝王、玉荷包中分别含有58、57、47、28、39种香气成分;五种荔枝共有的主要香气成分有1-甲氧基-2-丙醇、乙偶姻、3-甲基-2-庚醇、1-庚烯-3-醇、芳樟醇、2-乙基-2-丁烯醛、β-蒎烯、柠檬烯、巴伦西亚桔烯等,但其相对含量差异很大;此外,各品种也具有自己独特的香气成分。

Abstract: The aromatic compositions of five breeds of litchi were analyzed by SPME/GC-MS methods. The results indicated that the differences of aromatic constituents in composition and relative content in five breeds of litchi were significant . 58, 57, 47, 28 and 39 kinds of aromatic components were identified fro‘mfeizixiao’‘,heiye’‘,baila’‘,lizhiwang’ and ‘yuhebao’respectively. 1-methoxy-2-propanol, acetoin, 3-methyl-2-heptanol, 1-hepten-3-ol, linalool, 2-ethyl-2-butenal, β-pinene, limonene, valencene etc were identified in all five breeds, but their relative contents showed considerable differences. In addition, every breed of litchi has its particular aromatic components.
