摘　　要：在前期搭建好的简易动态顶空固相萃取装置的基础上,将通气方式从吹扫式改为抽吸式,考察抽气流速、抽气时间、吸附介质、解析溶剂、脱附过程对分析结果的影响,并使用气相色谱-质谱联用仪对7种合成香料进行检测。最后将优化后的方法应用于天然金桂干花挥发性成分的检测中,检测出的物质数量和总峰面积皆优于前期吹扫式装置,表明此装置可为天然香料的香气成分的分析提供经济、便捷、有效的解决方案。Based on the simple dynamic headspace solid phase extraction apparatus built in our previous study,this study changed the ventilation method from purging to exhausting,investigated the effects of exhausting gas flow rate,exhausting time,adsorption medium,desorption solvent and desorption process on the analytical results,and utilized gas chromatographymass spectrometry to detect 7 synthetic aroma components.Finally,the optimized method was applied to the detection of volatile components of dried flowers of Osmanthus fragrans,resulting in greater number of detected substances and the total peak area compared with those of the previous method,indicating the apparatus developed in this study to be an economic,simple and effective solution for natural aroma components analysis.
