摘　　要：建立一种基于质子转移反应-飞行时间质谱(PTR-TOF-MS)的不同产地金线莲快速鉴别方法.采用PTR-TOF-MS对不同产地(福建、广西、台湾)的66个金线莲样本进行指纹图谱采集.将检测到的指纹图谱与化学计量学结合,开发一种可应用于不同产地金线莲快速准确鉴定的新技术.结果表明,使用PCA主成分分析方法提取主成分数为4、判别分析方法为FDA(Fisher判别分析法)时建立的数学分类识别模型性能最好,识别准确率达到97.0%,可以实现不同产地金线莲的有效判别.A rapid identification technology for anoectochilus from different places based on proton transfer reaction-time-of-flight mass spectrometry had been developed in this study.PTR-TOF-MS was used to collect fingerprints of 66 anoectochilus samples from different origins(Fujian,Guangxi,Taiwan),and the detected fingerprints and chemometrics were combined to develop a new technology that can be applied to rapid and accurate identification of anoectochilus in different origins.The experimental results showed that the number of principal components extracted by principal components analysis(PCA)was 4,and the mathematical classification and recognition model established when the discriminant analysis method was Fisher discriminant analysis(FDA)had the best performance,with a recognition accuracy of 97.0%,which can realize effective discrimination of anoectochilus from different origins.
