| Abstract: | Objective: To establish an accurate and effective method for determination of heavy metal contents in Danshen.Method: The Danshen sample was treated with microwave digestion-graphite furnace method,and then plumb(Pb),cadmium(Cd),cuprum(Cu) and arsenicum(As) contents in Danshen were determinated with atomic absorption spectrometry(AAS).Hydrargyrum(Hg) content was determinated with cold atomic absorption spectrometry.Results: Heavey metal contents in Dan-shen samples tested were all under the limited lines.Conclusion: This method is accurate,simple and effective for determinating Pb,Cd,As,Cu,Hg in Danshen. |
