Determination and Analysis of Trace Elements in Different Germplasms of Zanthoxylum bungeanum
Identifying and classifying trace elements in the pericarp of Zanthoxylum bungeanum is fun-damental to the development and utilization of its germplasm resources.Analyzing the differences in trace element content among different Zanthoxylum germplasm can help select superior varieties local-ly.This paper uses 15 specific germplasm samples of Zanthoxylum bungeanum collected from the Zan-thoxylum Experimental Station in Hancheng,Shaanxi Province as experimental materials.The ICP-MS method was employed to determine the content of 10 trace elements,including mineral elements(Fe,Mn,Zn,Cu)and heavy metal elements(Al,As,Cr,Cd,Pb,Hg),in Zanthoxylum.The results indicate that the content of mineral elements in Zanthoxylum is Fe>Mn>Zn>Cu.The total content of the four mineral elements is the highest in ZB7(Laiwu Dahongpao),ZB15(Space Zanthoxylum),ZB2(Hancheng Dahongpao(grafted)),and ZB1(Gelao non-spiny Zanthoxylum).For heavy metal elements,the content is Al>Cr>Pb>Cd>As>Hg.By considering the total metal content and the target risk coefficient,it is concluded that ZB3(Hancheng Dahongpao(excellent strain)),ZB10(Lai-wu Dahongpao),ZB11(Yangquan Dahongpao),and ZB6(Linyi Xiaohuajiao)have lower heavy metal content,lower overall risk coefficients,lower cancer risks,and better quality.
