[Determination of mineral elements in Bupleurum based on ICP-AES].

UNLABELLED: 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. CONCLUSION: In Bupleurum, the content, accumulation and proportion of mineral elements were difference at different habitat.
