摘要: In the present paper, the contents of 18 mineral elements in milled and brown rice of 55 accessions elite cultivars as well as corresponding soils were determined by ICP-AES technique. The method proves to be simple, rapid, highly sensitive and accurate, and can be used to determine many elements at the same time, its recovery ratio obtained by standard addition method ranged between 93.1% and 110.2%, and its RSD was from 0.8% to 5.1%. The analytical results showed that 18 mineral elements (S, Mo, Ba, Ni, Fe, Cr, Na, Al, Cu, P, Sn, Zn, B, Mn, Mg, Ca, Sr and K) are the important active compositions of functional rice, and their mean contents in milled rice are in the order of P>K>S>Mg>Ca>Zn>Na>Al>Mn>Fe>Cu>B >Mo>Ni>Sn>Cr>Ba>Sr, in brown rice in the order of P>K>Mg>S>Ca>Zn>Mn>Al>Na>Fe>Cu>B>Mo>Sn> Ni>Cr>Ba>Sr, but in soil in the order of Fe>Al>Ca>K>Mg>P>S>Mn>B>Na>Ba>Zn>Cr>Cu>Ni>Sn>Mo> Sr; 16 mineral elements in milled and brown rice (except for S and P) are clearly lower than that in soils. The correlation of 8 microelements (Mo, Ni, Cr, Sr, Mn, Zn, Cu and NO in milled and brown rice is closer than that of 6 macroelements (P, K, Mg, Ca, S and AD. There are rich Fe, Al and Ca in Yunnan soils, but 4 elements (P, K, Mg and S) are in high priority in milled and brown rice; The milled rice used for the staple is easier to place a premium on chronics than brown rice. The above results provided reliable data and theory bases for genetic breeding and production of functional rice, and for further solving the chronics and the malnourished problems with insufficient Fe, Zn and Ca for 4 billion people in the world.
