摘　　要：为探究3种太和香椿挥发性成分差异,并建立一种香椿品种的快速鉴别方法,该研究采用气相色谱-离子迁移谱技术对3种香椿中的挥发性成分进行检测分析。根据各组分的保留时间和离子漂移时间,对检测出的物质进行定性分析,确定化合物名称。利用LAV软件中的Gallery Plot插件,构建香椿样品的挥发性成分指纹图谱,比较不同香椿样品的挥发性成分差异。定性分析结果显示,3种香椿中共鉴定出挥发性物质47种,相对含量最高的为醇类化合物,以2-己烯醇最高,表现为草木香和果香。由主成分分析图可以直观看出,3种不同香椿样品得到明显区分,不同样品间具有明显的归属区域。该研究可以为香椿的快速鉴定和分类提供了一种简单、快速的方法,具有较大的应用前景。The aim of this study was to explore the differences of volatile components in three types of Toona sinensis from Taihe and to establish a rapid method of classifying the marking variety of the Toona sinensis.In this study,the characteristic flavors of three types of Toona sinensis were analyzed by gas chromatography-ion mobility spectrometry(GC-IMS).Specifically,qualitative analysis was conducted on the detected substances and the name of the compounds according to the retention time and ion drift time of each volatile component.Furthermore,three Toona sinensiss samples were selected to establish volatile components fingerprints based on the results of clustering analysis by Gallery Plot in Laboratory Analytical Viewer software.The results of the qualitative analysis showed that a total of 47 volatile odorants were identified in three types of Toona sinensis,and the highest relative content of volatile components were alcohols among which 2-hexenol was the highest,which showed herbaceous aroma and fruit aroma.Additionally,three Toona sinensis could be clearly distinguished through theprincipal component analysis(PCA)results,and each sample could be exhibited an obvious region in the plots.In conclusion,the presented method was proved to be a simple and rapid method of the classification and identification of Toona sinensis,which has a great application prospect.
