Abstract：The contents of K, Ca, Mg, Fe, Cu and Pb in ten coriander samples from two kinds of different growing regions was evaluated in HClO4-HNO3 digestive system by using wet digestion and flame atomic absorption spectrophotometry (FAAS). The results showed that two kinds of ten coriander samples contained high contents of K, Ca, Mg and Fe of human requirements, as well as a certain amount of heavy metal elements Cu and Pb. But the element contents of ten coriander samples from different growing regions had the certain differences. The certain differences in element contents were also observed between the leaves and stems of ten coriander in the same growing region ,in addition to Mg,the content of other five elements in the leaves were higher than that of stem,standard addition recovery experiment showed that the average recovery 84%~107% and the relative standard deviation 0.5%~1.3% of Fe and Cu elements.The experimental method was accurate and the results were reliable .
