摘　　要：为了探讨矿质元素技术在杭白菊原产地溯源中的可行性,利用电感耦合等离子体质谱仪(ICPMS)测定杭白菊中Cd、Pb、Cr、Zn、Ni、Co、Rb、Sr、Ba、Ga和V共11种矿质元素的含量,结合典则判别分析建立杭白菊产地判别模型。结果表明,用于建立杭白菊原产地判别模型的矿质元素为Pb、Sr、Ba、Ga和V,原始和交叉验证总体正确判别率分别为100%和97.1%。用于建立桐乡市三个种植区杭白菊判别模型的元素为Cd、Pb和Rb,原始和交叉验证总体正确判别率分别为76.7%和70.0%。因此,矿质元素指纹技术可以用于杭白菊的原产地保护以及原产地不同产区的溯源。The aim of this work was to investigate the feasibility of mineral elements in traceability of Hangzhou white chrysanthemum. The concentrations of 11 mineral elements （Cd, Pb, Cr, Zn, Ni, Co, Rb, Sr, Ba, and V） were determined with inductively coupled plasma mass spectrometry （ICP-MS） , and then the concentrations of all elements were analyzed by canonical discriminant analysis （CDA）. The results showed that the elements used to develop the discriminant model of Protected Designation of Origin （PDO） were Pb, Sr, Ba, Ga, and V, and the original and cross- validated classification rates were 100% and 97.1% , respectively. The elements used to develop the diseriminant model of different growth areas in Tongxiang were Cd, Pb, and Rb, and the original and cross-validated classification rates were 76.7% and 70.0% , respectively. As a result, the fingerprints of mineral elements could be used to the protection of PDO of Hangzhou white chrysanthemum and the discrimination of Hangzhou white chrysanthemum in different growth areas of Tongxiang.
