| Abstract: | Eight metal elements such as potassium,calcium,sodium,magnesium,zinc,manganese,iron and copper from hanzhong corydalis sample were determined by FAAS with microwave digestion.The concentration of potassium,calcium,sodium,magnesium,zinc,manganese,copper and iron were 2033.97,600.87,1395.55,494.88,220.36,107.75,39.68mg/kg and 2462.79mg/kg,respectively.The relative standard deviations were 0.0356%—4.4288% and average recovery were 96.8%—101.2%.This method is simple and sensitive for determination of trace elements from medicinal herbs. |
