| Abstract: | Objective: To determine the content of Pb, Cd, Hg, As and Cu in Polygonum perfoliatum from different places and evaluate their quality. Method: The samples were digested and detected by atomic absorption spectrophotometry and atomic fluorescence, and the results measured were treated by mathematical statistical software cluster analysis. Result: The content of Cd and Hg was over the relevant standards, the exceeding rate was Cd 73.33% and Hg 6.67% respectively. Conclusion: The content of Pb, As and Cu in Polygonum perfoliatum from different places is accorded with the correlative standards, while the content of Cd and Hg from some places exceeds the correlative standards. |
| Keywords: | Polygonum perfoliatum atomic fluorescence spectrometry atomic absorption spectrophotometry heavy metal determination of content absorption spectrophotometry |
