摘　　要：研究建立三七产地判别技术,为保护地理标志产品、追溯三七产地来源提供理论依据。采集云南省60个春三七样本,采用电感耦合等离子质谱仪(ICP-MS)测定春三七块根中44种矿质元素含量,对各片区样本中矿质元素含量进行方差分析、主成分分析和判别分析,建立春三七产地判别模型并验证。结果表明,春三七块根中13种矿质元素在不同片区间存在差异;春三七块根矿质元素含量和组成在不同片区间具有各自的地理指纹特征,对有明显差异的矿质元素进行逐步判别分析,筛选出K、Ca、Mg、Mn、Mo、Co和Sc 7种元素并建立判别模型;对不同片区的春三七块根原始样本进行回代检验和交叉检验,得到整体判别率分别为80.0%和71.7%。利用矿质元素指纹特征结合化学计量学方法可以对不同片区的春三七产地进行鉴别。A method for geographical origin discrimination of Panax notoginseng was established to provide technical support for the protection of geographical indication products and for tracing the geographical origin of agricultural products.Sixty samples of spring Panax notoginseng were collected,inductively coupled plasma mass spectrometry was used to determine the contents of 44 mineral ele⁃ments in the main root of spring Panax notoginseng,and analysis of variance,principal component analysis and discriminant analysis were carried out to develop and validate the discriminant model.The results showed that,the contents of 13 mineral elements in sam⁃ples were different among four producing areas.The content and composition of mineral elements in the root of spring Panax notogin⁃seng had their own geographical fingerprint characteristics in different sections.Through the stepwise discriminant analysis,K,Ca,Mg,Mn,Mo,Co and Sc were selected for the discriminant model from different elements.The overall correct discrimination rates for original spring Panax notoginseng samples from different geographical origins in back substitution and cross validation tests were 80.0%and 71.7%,respectively.The mineral elements fingerprint analysis combined with chemometrics could be used to distinguish the geographical origin of Panax notoginseng from different producing areas.
