Determination and Comparison of Content of Trace Elements in Polygonum perfoliatum L.from Different Origins
摘要
Abstract
[Objective] The research aimed to study the content of trace metal elements of Fe,Cu,Zn,Mg,Mn and Ca in Polygonum perfoliatum and compare the differences from different origins.[Method] The samples were smashed,sifted and dried,and then dissolved by microwave digestion system.The standard solution of the trace elements were prepared and the linear regression equation was established.The absorbance of each samples was measured by tihe atomic absorption spectrometry,and the content of each trace element was obtained.[Result] The recovery rate of six trace elements was between 98.0％-103.8％ and met the requirements of the determination.The content of Ca was highest and the content of Cu was lowest in Polygonum perfoliatum.The content of Ca and Fe in Polygonum pe~oliatum from Jiangxi Ganzhou was more higher then which from Sichuan Province,but the content of Cu,Zn,Mg,Mn was lower than which from Sichuan Province.[Conclusion] Using this method to measure the trace metal elements in Polygonum perfoliatum,the accuracy is high.The content of trace metal elements in Polygonum perfoliatum had much difference which from Jiangxi Ganzhou and Sichuan Province.关键词
