本研究调查了１０种硒营养物，通过ＧＦ／ＡＡＳ和ＨＰＬＣ／ＩＣＰ／ＭＳ方法确定总硒浓度及其化学形式。在调查的硒营养物中，发现总硒浓度大体与供应商的说明一致。然而这些硒营养物中硒的化学形式却相当不同。硒酸盐是其中４种硒营养物中硒存在的唯一形式。一种营养物中硒以硒化蛋氨酸的形式存在。在其他５种硒营养物中则检测到亚硒酸盐，硒酸盐，硒化胱氨酸，硒化蛋氨酸及几种未知化合物。
This study investigated 10 selenium nutrients and determined total selenium concentrations and their chemical forms by GF / AAS and HPLC / ICP / MS methods. Among the selenium nutrients investigated, it was found that the total selenium concentration was generally in agreement with the supplier’s instructions. However, the chemical forms of selenium in these selenium nutrients are quite different. Selenate is the only form of selenium present in the four selenium nutrients. Selenium is a form of nutrients in the form of selenomethionine. Among the other five selenium nutrients, selenite, selenate, selenated cystine, selenomethionine and several unknown compounds were detected.
