Setting up a measurement procedure based on electro thermal wet digestion and ICP-MS（Inductively Coupled Plasma Mass Spectrometry） to determine 14 mineral elements of rice. Verified by methodology, the accuracy and precision of our method are up to national standards. The linear relationship for 14 mineral elements which concentrations are limit of quantitation to 10 000 μg/L are good, and the detection limits are 0.002～1 mg/kg, high sensitivity. Making 64 rice samples from those rice which collected from 18 species of rice in 6 areas in Jilin city, Jilin province, then determined 14 mineral elements of those rice samples by established method, the mineral element contents and differences of polished rice and brown rice from different origins were compared. Analysis showed that the contents of K, Ca, Mg, Mn which are essential for human health in the brown rice are higher than those in the polished rice. The contents of Al, Na, Cu, Zn, Se, Fe in the brown rice are little higher than polished rice. There were no significant differences between the brown rice and the polished rice in the contents of As, Cr, Cd, Pb which are heavy mental elements. There was a little difference between the brown rice and the polished rice from different origins in the contents of K, Ca, Mg, Al, Se, Cd. There was a little difference between the brown rice from different origins in the contents of Zn, Pb, Fe. There was a little difference between the polished rice from different origins in the contents of Mn, As, the differences between the two elements in brown rice are great. There was a great significant difference between the brown rice and the polished rice from different origins in the contents of Na, Cu, Cr.
