摘　　要：利用主成分分析对11个不同产地枸杞子中的5种微量元素和黄酮含量进行分析,找到微量元素和黄酮的含量与枸杞子质量优劣的相关关系,得到不同产地的枸杞子质量优劣的综合排名.然后利用聚类分析对11种不同产地枸杞子进行聚类,结果恰好与主成分分析结果一致,说明主成分分析法所建的枸杞质量优劣评价模型稳定可靠,可以为枸杞子质量优劣评价研究提供一定帮助.By using principal component analysis to analysis the five kinds of trace elements and flavones in the fruit of Chinese wolfberry form 11 different origins,we found the relationship between the content of trace elements and flavones with quality of the fruit of Chinese wolfberry,getting a comprehensive ranking of different origins of the fruit of Chinese wolfberry.Then using cluster analysis to deal with the data,we found that clustering results of wolfberry fruit in different regions are consistent with the principal components.The Chinese wolfberry quality evaluation model which is built by principal component analysis（PCA）is stable and also can provide certain help for the research of quality evaluation of the fruit of Chinese wolfberry.
