摘　　要：目的建立一种基于电感耦合等离子体质谱法(inductively coupled plasma mass spectrometry,ICP-MS)的河北鸭梨产地溯源模型。方法对鸭梨中40种矿质元素(Ag、As、Al、Au、Ba、Cr、Cd、Ce、Co、Cs、Dy、Er、Eu、Gd、Ge、Ho、Lu、Li、La、Mo、Ni、Nd、Pb、Pd、Pt、Pr、Rb、Sc、Sn、Sb、Sm、Sr、Tm、Tl、Tb、Ti、V、W、Yb、Y)进行分析。通过方差分析、相关性分析、聚类分析和判别分析等数据统计方法,确定不同产地鸭梨中元素的差异性,建立了依据Ba、Ge、Ni、Pb、Pd、Ti 6种元素的溯源模型。结果通过建立的模型可以成功地对鸭梨产地进行判别,判别正确率达到97%。结论本研究建立的基于矿质元素分析溯源模型能够对河北鸭梨进行快速、有效的产地溯源,为产品打假提供了强有力的技术支撑。Objective To establish a geographical origin traceability model to trace the origin of Hebei Province Yali based on inductively coupled plasma mass spectrometry(ICP-MS).Methods Forty kinds of mineral elements,including Ag,As,Al,Au,Ba,Cr,Cd,Ce,Co,Cs,Dy,Er,Eu,Gd,Ge,Ho,Lu,Li,La,Mo,Ni,Nd,Pb,Pd,Pt,Pr,Rb,Sc,Sn,Sb,Sm,Sr,Tm,Tl,Tb,Ti,V,W,Yb and Y in Yali were analyzed.The variance analysis,correlation analysis,cluster analysis and discriminant analysis were adopted to determine the differences of elements in Yali from different areas,and the geographical origin traceability model was established based on the content of Ba,Ge,Ni,Pb,Pd and Ti.Results The established model in this study could successfully discriminate the producing area of Yali,and the discriminant accuracy reached 97%.Conclusion The traceability model based on mineral elements established in this study can quickly and effectively trace the origin of Hebei Province Yali,which provides strong technical support for the product anti-counterfeiting.
