The contents of total Se and of inorganic and organic Se species, as well as the contents of proteins, chlorophylls, carotenoids, and phenolic acids, were measured in 10-day old sprouts of rice ( Oryza sativa L.) obtained with increasing levels (15, 45, 135, and 405 mg Se L) of sodium selenite and sodium selenate and with distilled water as control. Increasing Se levels increased organic and inorganic Se contents of sprouts, as well as the content of phenolic acids, especially in their soluble conjugated forms. Moderate levels of sodium selenite (i.e., not higher that 45 mg L) appeared the best compromise to obtain high Se and phenolic acid yields together with high proportion of organic Se while limiting residual Se in the germination substrate waste. Se biofortification of rice sprouts appears a feasible and efficient way to promote Se and phenolic acid intake in human diet, with well-known health benefits.
以蒸馏水为对照，用亚硒酸钠和硒酸钠（浓度分别为15、45、135和405 mg Se/L）处理，测定了10日龄水稻（Oryza sativa L.）芽苗中总硒、无机硒和有机硒形态的含量，以及蛋白质、叶绿素、类胡萝卜素和酚酸的含量。硒水平的增加提高了芽苗中有机硒和无机硒的含量以及酚酸的含量，尤其是可溶性共轭形式的酚酸含量。适量的亚硒酸钠（即不高于45 mg/L）似乎是获得高硒和酚酸产量、高比例有机硒以及限制发芽基质废弃物中残留硒的最佳折衷方案。水稻芽苗的硒生物强化似乎是一种可行且有效的方法，可促进人类饮食中硒和酚酸的摄入，具有众所周知的健康益处。
