Abstract：The contents of potassium, calcium, magnesium, iron, manganese, copper, zinc and chromium in 11 kinds of Chinese traditional medicines such as Danshen, Gouqizi, Dangshen, Jiaogulan, Dongchongxiacao, Huangqi, Rougui, Xixin, Longdancao, Shanzhuyu and Duzhong were determind by flame atomic absorption spectrophotometry, in order to study the interrelation between metal elements and the therapeutic effect through the method of blurred classification. The results showed that the cluster in 7 kinds of medicines was similar when the relative coefficent was 0.50;cluster in 3 kinds of medicines was similar when the relative coefficent was 0.65;the cluster in 2 kinds of medicines was similar when the relative coefficent was 0.75. When the contents of metal elements are rich and the relative coefficient is considerably great, their therapeutic effect is similar. This suggests that trace elements have much to do with the therapeutic effect. The study provides new useful data for research on new types of medicines, and developing a new method for evaluating quality of Chinese tradition medicines.
