微波消解-电感耦合等离子体质谱仪测定藏药黑果枸杞中5种元素含量

目的：根据《中华人民共和国药典》（简称《中国药典》）通则2321，为黑果枸杞药材质量控制和安全用药提供可靠的依据。方法：采用微波消解-电感耦合等离子体质谱法，对16个不同产地黑果枸杞样品中铅、砷、镉、铜、锑5种元素含量进行测定，并参照《药用植物及制剂进出口绿色行业标准》展开评价。结果：所测定16个不同产地黑果枸杞中铅、砷、镉、铜、锑含量大部分符合《中国药典》和《药用植物及制剂进出口绿色行业标准》限量标准。结论：微波消解-ICP-MS法可快速测定黑果枸杞中5种元素含量。

Objective: According to the general chapter 2321 of Chinese Pharmacopoeia,to provide a reliable basis for the quality control and safe use of Lycium ruthenicum.Methods: Contents of five metals(Pb,As,Cd,Cu,and Sb) in Lycium ruthenicum from different habitats were determined by microwave digestion-ICP-MS.And the results were evaluated by The Import and Export Green Industry Standard of Medicinal Plants and Preparation.Results: A majority of the determination results of Pb,As,Cd,Cu,and Sb in 16 L.ruthenicum from different habitats were below the limit set by Chinese Pharmacopoeia and The Import and Export Green Industry Standard of Medicinal Plants and Preparation.Conclusion: Microwave digestion-ICP-MS can determine the content of five metals in L.ruthenicum quickly.
