| Abstract: | A good method was studied for determining Cu、Fe、Mn、Zn、Ni in the skin of stem,the leaf and the skin of root of honokiol obtained from Qinba Mountains by AAS with microwave digestion.In the best conditions of instrument,the recoveries of standand addition of these analytical elements were in the range of 98.8% to 108%.The method is simple,rapid and convenient with high accuracy and good precision,and has been applied to the determination of actual samples with satisfactorily results.The results provided useful data for the further research onhonokiol. |
