Identification of Xinhui Chenpi(Citri Reticulatae Pericarpium)by Gas Chromatography-Ion Mobility Spectrometry Combined with Chemometric Analysis
摘要
Abstract
Gas chromatography-ion mobility spectrometry(GC-IMS)was used to determine the flavor components of Citri Reticulatae Pericarpium(Chenpi)from 10 different geographical origins including Xinhui.To establish a method for the identification of Xinhui Chenpi,the 75 identified flavor components were analyzed by principal component analysis(PCA)and partial least squares discriminant analysis(PLS-DA).The results showed that the proposed method could distinguish Xinhui Chenpi from those from other regions.Meanwhile,by analyzing the variable importance in projection(VIP),we selected 20 key characteristic markers to distinguish Xinhui Chenpi from other Chenpi.In conclusion,the combined application of GC-IMS and PLS-DA allows the accurate identification of Xinhui Chenpi,providing a new technical reference for the protection and origin tracing of Xinhui Chenpi as a national geographical indication product in China.关键词
