【目的】测定富硒米中某些化学形态硒的含量，为将富硒米用于肿瘤预防提供科学根据。【方法】 2,3-二氨基萘荧光分析法测定富硒米中总硒、无机硒、有机硒含量；CNBr-2,3-二氨基萘荧光分析法测定硒蛋氨酸中的硒含量。【结果】夏、秋季收获的富硒米中总硒含量分别为（2.71±0.97） μg/g，（9.87±1.18） μg/ g，均大大地高于普通米，P<0.001；有机硒含量分别为2.68 μg/g，9.77 μg/g，均占总硒含量的99%以上；富硒米中的有机硒主要成分为硒蛋氨酸，含量分别为（1.45±0.67） μg/g，（4.96±0.98） μg/g，它们占总硒含量的53.5%, 50.5 %。【结论】富硒米中的硒绝大部分是天然有机硒，有机硒的主要成分是硒蛋氨酸。

【Objective】 Selenium (Se) contents of some chemical forms as total Se,inorganic Se,organic Se and selenomethionine (SeMet) in rice e nriched-Se were determined, in order to provide scientific basis for applying r ice enriched-Se to cancer prevention. 【Methods】 Fluorometric determination wi th 2,3-diaminonaphthalene (2,3-DAN) for total Se, inorganic Se and organic Se, and with CNBr-2,3-DAN for SeMet. 【Results】 Total Se contents of rice enrich ed-Se reaping in summer and autumn were (2.71±0.97) μg/g, (9.87±1.18 ) μg/g, respectively, both higher than that of ordinary rice (P<0.001); the organic Se occupying over 99% of total Se were 2.68, 9.77 μg/g, respectively . Main component of the organic Se was SeMet, and its Se content (Se-SeMet) was (1.45±0.67) μg/g for rice enriched-Se reaping in summer, (4.96±0.98) μ g/g in autumn,and their contents/total Se contents were 53.5, 50.5 %, respecti vely. 【Conclusions】 Most part of Se in rice enriched-Se was natural organic Se and main component of the organic Se was SeMet.
