摘要
The contents of As,Cd,Hg and Pb in 27 Chinese medicinal herbs were determined by ICP-MS with microwave assisted digestion.Cluster analysis was applied to study the distribution characteristics of As,Cd,Hg and Pb in different kinds of Chinese medical herbs from different sources.The result of cluster analysis showed that the contents of As,Cd,Hg and Pb from different sources were significantly different.It is helpful in the quality control and source identification of Chinese medicinal herbs.
