Abstract:

Taking Panax notoginseng，Aucklandia lappa Decne.，Rhizoma paridis，Poria cocks and Rhizoma coptis as materials,content of cadmium(Cd) and lead(Pb) in 5 different Chinese herbal medicine after separating and enriching with sulfhydryl cotton by flame atomic absorption spectrometry (FAAS) were determined,the enriching and eluting conditions were studied.The results showed that the precision relative standard deviations were between 0.34% and 2.86% for determining of Cd and Pb by this method，and the spike recoveries range from 96.32% to 103.70%.The results indicated that the method was reasonable well for determining content of Cd and Pb in Chinese herbal medicine.
