中国人. 采用顶空固相微萃取和气相色谱质谱联用技术(HS-SPME―GC―MS)分析‘绿化9号’桃果实的香气成分。结果表明:在‘绿化9号’桃果实中共鉴定出9类69种化合物,占总峰面积的87.22%,主要是挥发性醛类、醇类、酯类、酮类和烃类化合物。(E)-2-己烯醛、4,4′-(1-甲基乙基)二苯酚、δ-十二内酯、邻苯二甲酸-1-丁基-2-(8-甲基)壬基酯、γ-癸内酯、(Z)-乙酸-3-己烯醇酯、乙酸己酯、β-紫罗兰酮等相对含量在1%以上的成分占芳香物质总量的83.71%,是‘绿化9号’桃果实的主要香气成分。乙酸-2-甲基环戊酯、丁二酸-二(2-甲基)乙酯等在桃果实中首次报道的物质,可能是‘绿化9号’桃果实的特有香气成分。[著者文摘]

Results showed that 69 aromatic components belonging to 9 categories were identified, which accounted for 87.22% of the total peak area. The major constituents were aldehydes, alcohols, esters, ketones and hydrocarbons, etc. (E)- 2-hexenal, 4,4′-(1-methylethylidene) bis-phenol, δ-dodecalactone, 1,2-benzene dicarboxylic acid, butyl 8- methylnonyl ester, 7-decalactone, (Z)-acetate-3-hexen-1-ol, acetic acid hexyl ester, β-ionone, etc. , were main aroma components. Cyclopentanol,2-rnethyl , acetate, cis-, bis(2-methylpropyl)ester, etc., might be unique aroma components of ‘Green No. 9 ’peach fruit.
