    摘要:

    【目的】探明‘观音绿’荔枝的香气成分.【方法】采用顶空固相微萃取法(Headspace solid-phase microextraction, HS SPME)和气-质联用(GC-MS)技术对‘观音绿’荔枝的香气物质进行定性和定量分析.【结果和结论】在‘观音绿’成熟荔枝果实中共检出66种化合物,其中:烯类20种,醇类11种,酯类11种,酮类3种,烃类6种,醛类4种,芳香族化合物2种,其他化合物10种.‘观音绿’荔枝的主要香气成分是柠檬烯、甲基丁烯醇、萜品油烯、月桂烯、乙酸乙酯、梨醇酯、橙花醇、3-甲基-3-丁烯-1-醇、1-辛烯-3-醇、δ-愈创木烯等.‘观音绿’荔枝品质特优可能与其香气成分中烯类的种类和相对含量有关.

    Abstract:

    【Objective】The volatile components from ‘Guanyinlü’ litchi fruit were detected .【Method】Qualitative and quantitative analyses were carried out using headspace solid-phase microextraction (HS SPME) and gas chromatography-mass spectrometry(GC-MS). 【Result and conclusion】A total of 66 volatile components were detected in ripe ‘Guanyinlü’ litchi fruits, including 20 alkenes, 11 esters, 11 alcohols, 3 ketones, 6 alkanes, 4 aldehydes, 2 aromatic compounds and 10 others, among which the major components were D-limonene; 2-buten-1-ol, 3-methyl; cyclohexene, 1-methyl-4-(1-methyle thylidene); β-myrcene; ethyl acetate; 2-buten-1-ol, 3-methyl-, acetate; 2,6-octadien-1-ol,3,7-dimethyl-,(Z); 3-methyl-3-buten-1-ol; 1-octen-3-ol; azulene, 1,2,3,5,6,7,8,8a-octahydro-1, 4-dimethyl-7-(1-methylethenyl)-,[1S-(1α,7α,8aβ)]-. The quality of ‘Guanyinlü’ litchi might be related to the presence and relative content of the alkene of aroma components.
