| Abstract: | Chinese traditional herbal drugs of Rabdosia Iophanthoides and its relative species were treated with incineration,and the residues were dissolved by HNO3.Seven trace elements including calcium,magnesium,potassium,sodium,iron,manganese and copper in fifteen sample solutions were determined by flame emission spectrometry and flame atomic absorption spectrometry.The results show that the contents of calcium,magnesium,potassium,sodium,iron,manganese and copper are abundant,and the addition standard recoveries were in the ranges of 89.3%~100.0%,the standard deviation of measurement were in the ranges 0.2%~3.7%. |
