摘  要：
用顶空固相微萃取(head-space solid-phase microextractions,HS-SPME)和气相色谱质谱(gas chromatg-raphy mass spectrometrometry,GC-MS)联用技术对花牛苹果的香气成分进行了分析,共分离鉴定出了76种化学成分,其中酯类36种,占峰面积的45.71%;醇类13种,占峰面积的19.08%;醛类3种,占峰面积的9.62%;烯烃类3种,占峰面积的2.59%;其它物质占峰面积的12%,主要为酮类和烷烃类物质.选用OV-1701色谱柱、75μm CAR/PDMS萃取头,在萃取热平衡吸附时间25 min,温度40℃,解吸附时间3 min的试验条件下,得到的试验色谱峰保留时间和归一化面积的变异系数分别为0.08%~0.16%和2.72%~12.66%,且重复性良好.

摘  要：
Aroma components in the fruits of the apple cultivar Malus pumila′Huaniu′were determined and analyzed by headspace solid-phase microextraction(HS-SPME) coupled with gas chromatography/mass spectrometry(GC/MS)method.76 kinds of chemical constituents were isolated and identified,including 36 kinds of lipid accounting for 45.71 % of peak area,13 kinds of alcohols accounting for 19.08 %,3 kinds of aldehydes accounting for 9.62 %,3 kinds of alkenes accounting for 2.59 %,and all the other volatile components accounting for 12 %,such as ketones,alkanes and so on.The variation coefficients of retention time of chloroacetates and mormalized area were determined as 0.08 %～0.16 % and 2.72 %～12.66 % respectively,by using OV-1701 chromatographic column and 75 μm CAR/PDMS extraction fiber under the following experiment conditions:equilibrium adsorption time 25 min,temperature 40 ℃ and desorption time 3 min.The repeatability of the experiment was good.
