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.
【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.
