Determination of Mineral Elements in Bupleurum Based on ICP-AES

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·g-1,and 25.20 μg·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·g-1 and 50.04,32.21,15.43 μg·g-1 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 differenct at different habitat.
