                 摘要:应用顶空固相微萃取(headspace solid-phase microextraction,HS-SPME)结合气相色谱/质谱联用(GC-MS),
                 对古井贡酒中高温大曲进行分析,共定性出 108 种挥发性化合物。通过考察不同样品量下化合物的 β 值,在 35
                 和 50 mg 样品量下,建立了应用多次顶空固相微萃取(multiple headspace solid-phase microextraction,MHS-SPME)
                 对醛酮类、酚类、含氮类、呋喃类、内酯类、萜烯类等 46 种化合物进行定量的方法。该方法回收率为 76.83%~
                 133.11%、最低检测限(limits of detection,LOD)低于 103.818 ng/g、相对标准偏差(RSD%)小于 21.34%,具
                 有较好的灵敏度和重复性。实验结果表明 MHS-SPME 可用于大曲中这 46 种化合物的定量,化合物含量在
                 (3645.79±442.43)~(6.32±1.03)ng/g 之间。该方法为定量大曲中挥发性成分提供了新的思路,研究结果也为企
                 业完善大曲质量评价体系提供了数据支持。

                 Abstract:  Headspace  solid-phase  microextraction  (HS-SPME)  combined  with  gas  chromatography-mass
                 spectrometry (GC-MS) was used to analyze the medium high temperature Daqu in Gujing Gongjiu, and a
                 total  of  108  volatile  compounds  were  identified.  By  examining  the  β  values  of  the  compounds  under
                 different  sample  amounts,  multiple  headspace  solid-phase  microextraction  (MHS-SPME)  was  applied  to
                 quantify  the  aldehydes  and  ketones,  phenols,  nitrogen,  furans,  lactones,  terpenes  at  the  35  and  50  mg
                 samples, and a total of 46 compounds were quantified. The recoveries of the method ranged from 76.83%~
                 133.11%, the limits of detection (LOD) were lower than 103.818 ng/g, and the relative standard deviation
                 (RSD%)  were  less  than  21.34%,  which  showed  the  method  had  good  sensitivity  and  repeatability.  The
                 experimental  results  showed  that  MHS-SPME  could  be  applied  to  the  quantitative  analysis  of  these  46
                 compounds in Daqu. The contents of measured compounds ranged from (3645.79±442.43) to (6.32±1.03) ng/g.
