[Objective]To detect the copper,lead,chromium,arsenic and mercury contents in RADIX ARDISIAE CRENATAE in different production areas of Guizhou Province.[Method]RADIX ARDISIAE CRENATAE was treated by microwave digestion;the contents of copper,lead,chromium,arsenic and mercury were detected by atomic absorption spectrometry.[Result]Except the chromium content exceeded the standard,contents of the rest metals were all lower than the limited amount in Green Standards of Medicinal Plants and Preparations for Foreign Trade and Economy.The over standard rate was 37.5%.[Conclusion]This method was simple,rapid,accurate and could effectively detect the contents of copper,lead,chromium,arsenic and mercury in RADIX ARDISIAE CRENATAE.
[Method] RADIX ARDISIAE CRENATAE was treated by microwave digestion; the contents of copper, lead, chromium, arsenic and results were obtained by atomic absorption spectrometry. [Result] Except the chromium content exceeded the standard, contents of the rest metals were all lower than the limited amount in Green Standards of Medicinal Plants and Preparations for Foreign Trade and Economy. The over standard rate was 37.5%. [Conclusion] This method was simple, rapid, accurate and could effectively detect the contents of copper, lead, chromium, arsenic and mercury in RADIX ARDISIAE CRENATAE.
