| Abstract: | In this paper,Chloroform,hot water and ethyl alcohol with various concentration were employed to extract Mn?Cu?Fe?Ca?Mg and K in Largehead Actractylodes Rhizome,which were determined by flame atomic absorption spectrometry.the contents of referred elements in all extractants and residue were determined successfully.We found that 20% ethyl alcohol solution is most suitable to extract trace metals from the above Chinese herbal medicine.The element contents in this kind of solutions are about 1.5 times of those in chloroform extractant. |
