Determination of trace elements in Phellodendron chinese by FAAS

Ren Shu-lin

Abstract

Objective:To determine the trace elements in Phellodendron chinese,which would also supply useful data of the relation of the metal elements in corydalis and Medicinal function.Methods:The contents of trace elements in Phellodendron chinese by flame atomic absorption spectrophotometry.Results:The results showed that the recovery rate was between 98.0%～102.6%,the relative standard deviation(n=6) was between 0.90%～4.0%.Conclusion:The characteristic method is quick,simple and convenient,and the results are satisfactory.
