Determination of trace elements in Rhizoma Corydalis by FAAS

Xie Ai-yan

Abstract

Objective:To determine the trace elements in Rhizoma Corydalis,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 Rhizoma Corydalis by flame atomic absorption spectrophotometry.Results:The results showed that the recovery rate was between 99.00%～101.7%,the relative standard deviation(n=6) was between 1.49%～1.88%.Conclusion:The characteristic method is quick,simple and convenient,and the results are satisfactory.
