摘　　要：为了对比青海不同地区枸杞的品质,采用ICP-MS和ICP-AES法对青海省12个产地的枸杞果实中11种微量元素含量进行了测定,并选取人体必需的7种微量元素,结合SPSS统计软件进行主成分分析。结果获得了3个主成分方程,并建立了主成分对变量的回归方程,对比较青海不同地区枸杞优劣以及获得高品质枸杞具有重要意义,为青海枸杞的开发和利用提供了科学依据。For comparison of the quality of Lycium barbarum L.,the authors determined 11 trace elements in the fruits of Lycium barbarum L.from 12 different regions of Qinghai province by ICP-MS and ICP-AES.Meanwhile,7 trace elements essential for human body were selected to the object of principal component analysis by SPSS statistic software.Three principal component equations were obtained,and the regression equation related to principal component was also set up.The research is very important to quality analysis and to obtaining high quality Lycium barbarum L.,and provided science basis for the development and utilization of Lycium barbarum L.in Qinghai province.
