title: [The cluster analysis of trace elements in fructus cnidii from different region].
abstract: The contents of trace elements in Fructus Cnidii from different region were assayed by atom absorption spectrum and analyzed by cluster analysis methods. The results showed the contents of trace elements from different regions were different, which had some relativity with habitats, but should be further studied.
