摘　　要：以普通废橘子皮作为研究对象,采用顶空固相微萃取结合气相色谱-质谱对不同萃取头萃取的橘子皮挥发性物质进行研究。电子鼻分析发现传感器W3S、W2S、W5S和W1S对橘子皮样品的响应值较为明显,表明含N、O的杂环类化合物、烷烃类化合物、醇类化合物和部分芳香类化合物是橘子皮样品的主要挥发性物质。3种不同萃取头(50/30μmDVB/CAR/PDMS、65μmDVB/PDMS、100μmPDMS)在橘子皮中共检测出64种挥发性成分,其中50/30μmDVB/CAR/PDMS萃取头检测出挥发性化合物46种,65μmDVB/PDMS萃取头检测出挥发性化合物34种,100μmPDMS萃取头检测出挥发性化合物38种。在这些挥发性化合物中,烯烃类物质以及醇类物质的相对含量普遍较高。主成分分析(Principal Component Analysis,PCA)发现3种萃取头萃取出的挥发性化合物存在明显的差异。Taking ordinary orange peels as the research object, headspace solid phase microextraction combined with gas chromatography-mass spectrometry was used to study the volatile substances in orange peels extracted by different extraction heads. Electronic nose analysis found that sensors W3S, W2S, W5S, and W1S have obvious response values to orange peel samples, indicating that N, O-containing heterocyclic compounds, alkanes, alcohol compounds, and some aromatic compounds are mainly volatile substances in the samples of orange peel. Three different extraction heads(50/30μm DVB/CAR/PDMS, 65 μm DVB/PDMS, 100 μm PDMS) have detected 64 volatile components were detected by three different extraction heads(50/30 μm DVB/CAR/PDMS, 65 μm DVB/PDMS, 100 μm PDMS) in orange peel, 46,34 and 38volatile compounds were detected by extraction fiber of 50/30 μm DVB/CAR/PDMS, 65 μm DVB/PDMS 100 μm PDMS respectively. Among these volatile compounds, the relative content of alkenes and alcohols is generally high. PCA analysis found that the volatile compounds extracted by the three extraction heads are significantly different.
