摘　　要：为对荔枝新品种‘御金球’果肉中挥发性成分进行分析,采用顶空固相微萃取法和气质联用(HS-SPMEGC-MS)技术,结果共检测到烯类(73.87%)、酯类(4.38%)、醇类(3.12%)、醛类(0.81%)、酮类(0.14%)、酸类(0.19%)、烷烃类(0.57%)及其他成分10大类共52种化合物,其中烯烃类含量最高,共计24种。右旋大根香叶烯、α-衣兰油烯、1-甲氧基-3,7-二甲基-2,6-辛二烯、榄香烯、月桂烯、α-异松油烯、柠檬烯、香橙烯、γ-衣兰油烯、γ-杜松烯、α-蒎烯、(+)-环苜蓿烯,β-榄香烯、乙酸香茅酯、1-乙酰基-16,17-双脱氢-(9CI)-Curan-20-醇、(1a,3b,4b,6a)-4,7,7-三甲基二环[4.1.0]庚烷-3-醇、香叶醇、柠檬醛为其主要香气成分。而相对含量最大(20.16%)且具有抗菌作用的右旋大根香叶烯、抗菌抗氧化的柠檬醛、黄酮类的3',4',7-3-O-甲基槲皮素等物质的检出显示出‘御金球’荔枝具有潜在的药理及保健作用。The volatile compounds of pulp from new litchi cultivar‘Yujinqiu＇were extracted by headspace solid-phase microextraction and were identified by the analysis of gas chromatography-mass spectrometry（ HSSPME-GC-MS）.52 components from ten groups were indentified including terpenes（ 73. 87%）,esters（ 4.38%）,alcohols（ 3.12%）,aldehydes（ 0.81%）,ketones（ 0.14%）,acids（ 0.19%）,alkanes（ 0.57%） and other ingredients,among which 24 kinds terpenes had the highest Relative content and the major volatile components in‘Yujinqiu＇pulp were Germacrene-D,α-Muurolene,1-Methoxy-3,7-dimethyl-2,6-octadiene,Elemene,Myrcene,α-Terpinolen,DL-Limonene,Aromadendrene,γ-Muurolene,γ-Cadinene,α-Copaene,（ ＋）-Cyclosativene,β-Elemene,Citronellol acetate,Curan-20-ol,1-acetyl-16,17-didehydro-（ 9CI）,Bicyclo[4.1.0]heptan-3-ol,4,7,7-trimethyl-,（ 1a,3b,4b,6a）-（ 9CI）,Geraniol and Citral in‘Yujinqiu＇pulp. In addition,the detection of Germacrene-D with maximum relative content（ 20.16%） and antibacterial action,citral with antibacterial and antioxidant effects and the flavonoids 4H-1-Benzopyran-4-one,2-（ 3,4-dimethoxyphenyl）-3,5-dihydroxy-7-methoxy-all showed that‘Yujinqiu＇has the potential of pharmacology and health care.
