摘要：

目的:了解22个产地的黑果枸杞中主要矿质元素的分布特点。方法:22份黑果枸杞样品经微波消解法处理,用国家标准方法测定K、Ca、Na、Mg、Fe、Co、Zn、Mn、Cu、Cr、Ni、Pb和P元素的含量,用主成分分析(除Pb)进行产地综合排名并用聚类分析进行产地聚类。结果:黑果枸杞含有多种有益的矿质元素,且重金属Cu和Pb的含量符合《中国药典》安全标准。主成分分析结果显示,产自新疆的黑果枸杞样品综合得分较高,矿质元素含量较多;而产自西藏的黑果枸杞样品综合得分较低,矿质元素含量较少。聚类分析结果与主成分分析结果基本一致。结论:黑果枸杞含有丰富的矿质元素,但不同产地的含量不同,品质各异,可为其进一步的综合开发利用提供数据支持。
