摘　　要：采用火焰原子吸收分光光度法测定了陕北榆林的黑小米和黄小米,陕南安康的黑米和江米(白糯米)中Fe、Mn、Cu和Zn的含量,并比较了不同颜色谷物中微量元素的含量。结果表明,深色谷物中微量元素高于白色谷物,其结果可对健康饮食提供参考。Micro-elements including Fe, Mn, Cu, Zn and Ca in several grains with different colors were determined by AAS（atomic absorption spectrometry）. The black and yellow grains from Yulin and black rice and glutinous rice Ankang were an- alyzed. The results showed that contents of micro-elements in the darker grains were higher than those in white grains, pro- viding a reference for healthy diet.
