title: [Determination of mineral elements in Bupleurum based on ICP-AES].
abstract: ICP-AES technique was used to determine the mineral elements in Bupleurum at different habitat. The results show that: (1) In Bupleurum, the content and accumulation of K was the highest among 5 macroelements, the content and accumulation of Fe was the highest among 5 microelements. (2) In Bupleurum, the content of Ca, Mg, P, Na and Cu was high in habitat of Beijing, the content can respectively reach to 6.40, 3.84, 3.45, 4.97 mg x g(-1), and 25.20 microg x g(-1); while the content of K, Ca, Mg, P, Zn, Mn and Cu was low in habitat of Wanrong,and the content was only 12.43, 4.57, 1.92, 1.79 mg x g(-1) and 50.04, 32.21, 15.43 microg x g respectively. (3) In Bupleurum, the content of P : K, Zn : Fe, Cu and Mn was significantly different at different habitat, while Mg and Ca showed little difference.
  
  
  CONCLUSIONS
  In Bupleurum, the content, accumulation and proportion of mineral elements were difference at different habitat.
